[JENKINS-73242] Don't fail organization scan if a repository errors

[solonovamax]

Description

Don't fail organization scan if a repository errors. See JENKINS-73242 for further information.

Implementation details:
Before attempting any checks against the repository, run GHRepository.getSource(). This will cause the repository to attempt to populate all the needed data.
Sometimes this can fail, such as in the case where a repository was DMCA'd.
If it fails, catch that error and skip the repository.

I have not added a test case for this, as I'm not too familiar with the test framework.
However, if anyone else wants to add a test case, here is a request that can be used for one:

also, please do let me know if there is anything I should change/etc. as this is my first contribution to a jenkins plugin.

[solonovamax]

hey, is there anything blocking this from being merged?

I've been forced to use a locally built version of the plugin, as this is a major issue to me, and having to repeatedly go and rebuild on every update is incredibly annoying.
