feature: Augment default truststore by default, optionally limit to custom CA certs

[slowjoe007]

Continuation of PR #1937, considering the changes proposed in that PR.

Description

The change in feature #1863 did not cover the CLI feature of Bruno, bru. This feature adds that part and introduces a new command line option to bru CLI to control the way custom CA certificates are handled: replace or extend the default truststore.

The new CLI option is called --ignore-truststore and documented in both synopsis and readme.
This new option only is in effect, if a custom CA certificate is specified via option --cacert.

At the same time, this change inverts the default handling of specifying custom CA certificates in the GUI. Previously, the default truststore was replaced completely, if custom CA certificates had been specified. Now specifying custom CA certificates results in augmenting the default truststore: the setting "Keep default truststore" is selected by default.

Hi @mjhcorporate and @helloanoop, here are the promised changes (see #1937). I created a new PR for this.
The logic of extending or replacing the truststore is inverted now. This should be easier to consume.

The failing test of auth/inherit also fails in branch main. This error is not related to the changes made here.

auth/inherit auth/inherit Bearer Auth 200 (401 Unauthorized) - 175 ms
   ✕ assert: res.status: 200
      expected 401 to equal 200
   ✕ assert: res.body.message: Authentication successful
      expected 'Unauthorized' to equal 'Authentication successful'

@helloanoop, please, consider adding this PR for one of the next releases. It is done for 3 weeks. I just merged the branch with the latest updates of main, so the PR should be ready for merging.

Did the rebase exercise again. Would be great to have this missing feature of the CLI component considered for the next release, @helloanoop.
Thank you!
