Add Missing Endpoint Tests & Fix parameters.value bug

[MRichards99]

This PR will close #270

Description

This PR adds endpoint tests to match the example queries given in the example implementation of the search API. The linked issue shows which tests were missing, and below shows a list of those query names alongside the corresponding Pytest parameter names which I've added:

• Query datasets acquired using X-Ray Absorption - Search datasets with condition on techniques name (ICAT 5)
• Query datasets where the photon energy range is 880-990 eV - Search datasets with parameters include and conditions (between operator, A AND B AND C)
• Query datasets with a solid sample or copper - Search datasets with parameters include and conditions ((A AND B) OR (C AND D)
• Query datasets where temperature is below 80°C - Search datasets with parameters include and conditions (lt operator, A AND B AND C)
• Query datasets with files matching a string using full text search - Search datasets' files using full text search
• Query documents of type proposal containing my own data - Search documents with document condition, multiple includes (nested) and conditions on those with parameters include and conditions
• Query documents where wavelength is 1000-1100 nm - Search documents with parameters include and conditions (between operator, A AND B AND C)
• Query documents containing datasets where wavelength is 1000-1100 nm - Search documents with datasets.parameters include and conditions (between operator, A AND B AND C)
• Query documents investigating a particular sample using a certain technique - Search documents with multiple include and scopes (ICAT 5)

Two of the example queries are reliant on ICAT 5 - I've added these tests and added skips to them until ICAT 5 exists. In #310, we should unskip these tests. I've made a best attempt at writing the query parameters and the test data for those tests, but small adjustments will probably need to be made (e.g. when we know what the techniques test data will look like).

Whilst writing these tests, I came across a bug when a request contains a WHERE filter with a between operator on parameters.value. Query datasets where the photon energy range is 880-990 eV is an example where this bug would occur. This has been fixed in 3fe8dfe by detecting this use case and checking the type of the first value in the list (e.g. between [20, 30]). I added a test in test_search_api_where_filter.py to test this at the WHERE filter level; the endpoint tests added in this PR also test this at an endpoint level.

A fix version bump will be applied when merging this PR (print-version command currently says 4.1.2).

Testing Instructions

Test the parameters.value between operator has been fixed

• Review code
• Check GitHub Actions build
• If icatdb Generator Script Consistency Test CI job fails, is this because of a deliberate change made to the script to change generated data (which isn't actually a problem) or is here an underlying issue with the changes made?
• Review changes to test coverage
• Does this change mean a new patch, minor or major version should be made? If so, does one of the commit messages feature fix:, feat: or BREAKING CHANGE: so a release is automatically made via GitHub Actions upon merge?
• Additional tests should cover all the example queries in the example implementation of the search API
• A request with a WHERE filter on parameters.value that uses a between operator should return a 200 with relevant data
