Modernize project and make it buildable

[rzo1]

What does this PR do?

I checked out the repository to work on https://github.com/sweble/sweble-wikitext/issues/90 and wasn't able to build the project due to different issues.

Therefore, I went ahead to fix them:

• Move parent back to latest released version 3.0.8
• Manually overrides some outdated plugins / configurations
• Skip some checks as they cannot deal with Java 11 (due to old parent)
• Updates language level to 11
• Fix some deprecations

I guess all we need to merge this is just to get the CI to pass, no?

[rzo1]

The CI failed with something unrelated afair. Maybe you can retrigger?

[wetneb]

I don't have the option to re-trigger, perhaps because the last build is too old. Could you perhaps make a tiny irrelevant change? :-D

[rzo1]

@wetneb Can you approve the workflow? ;-)

is actually related.

[wetneb]

I do think it is related: you have removed fetch-depth: 0 from the git cloning options in the CI. Can you try adding it back?

@wetneb thanks for the hint, seems to work now
