Docblock Parser breaks on Exif module

8.x-1.x works: https://git.drupalcode.org/project/exif/-/blob/8.x-1.x/src/Controller/Ex...
8.x-2.x breaks: https://git.drupalcode.org/project/exif/-/blob/8.x-2.x/src/Controller/Ex...

Thanks for reporting @NickDickinsonWilde and for the example of working vs non-working page, that helped a lot.

I think the reason was the branch not having a core version value. I reviewed the code and saw that in this case, we were getting NULL where a string was expected, so I added a few fallbacks and checks for this and the page now renders as expected.

Related fixes:
When I set the project with the QuickWizard form, I saw that the core version is not set properly for the 8.x-2.x. There is actually a status message prompting users to review the value: Please review the "Core compatibility" fields in each branch..

This is due to the module wrapping the `core_version_requirement` in quotes. Checking other contrib modules, none of them have it.
In any case, and due to this, I added a little bit of code that should trim quotes and spaces from values, and log a message to the logger for strings that might not pass the Semver validation.

All of the above can be seen in the MR. Please review.

Yeah I saw that message about reviewing core compatibility. I thought I had but I guess I missed that one (I did add a bunch of things at once/in a row) - it was empty.
In any case, that looks good to me and resolves the issue, thanks.

Thanks for reviewing and confirming that it resolves the issue.
