[tests-only] Adjust minor words in API sharing test steps

[phil-davis]

Description

Minor adjustments to test step wording that was introduced in PR #38950

Note: there are a lot of uses of file|folder|entry or files|folders|entries in the core test code. But in owncloud/web we call "file or folder" a "resource", which is also the way we commonly refer to "file or folder" in reva, OCIS etc. So we should update that in the core tests to be consistent. But that can wait until after 10.8.0 is released - we don't want to do big test-code-refactoring until after release-10.8.0 branch is merged back to master
