Update to latest servlet api.

[MikeNeilson]

Changes javax to jakarta namespace.
Changes minimum Java to 11
Also updates Mockito

This should likely just be another branch to run in parallel, however I can't do that with a simple PR.

Fixes #15

[jamesward]

Thanks for this! Can you get CI passing?

[MikeNeilson]

that should work now, did run mvn verify locally but managed to forget about any action... whelp.

[jamesward]

Thanks. I think the action is using some other outdated stuff. Let me know if you want me to get it updated :)

i just did so in the branch.

[MikeNeilson]

well now i'm just confused but i don't use maven often so perhaps mvn verify and mvn test don't quite line up. I'll dig more.

[MikeNeilson]

Okay now it should work.

[jamesward]

Thanks for doing all this! I'll get a release out shortly.

[jamesward]

The release is now on Maven Central: org/webjars:webjars-servlet-6.x:1.7
Let me know if you have any problems. Thanks again!

[MikeNeilson]

No problem, thanks for jumping on the PR so fast!
