Java: remove SpringBootActuators query

[jcogs33]

Description

This PR removes the githubsecuritylab/java/spring-boot-exposed-actuators query. This query was added to the default code scanning query suite by github/codeql#18793 and released in CodeQL 2.21.0.

I will make follow-up PRs to update package dependencies for 2.21.0 (draft PR) and to publish a new release.

Consideration

• Does this need a change note? I see a Change notes section in CONTRIBUTING.md, but since the linked guide does not exist, I'm not sure if a change note is needed.
• I have not contributed to this repo before, so let me know if there's anything else I need to do.

Excellent!

Good question. It appears that this guide was merged around the time, where we added the experimental queries in the first place (at that time we didn't make any change notes). My best guess is that we don't need to add a change note (as this part of the documentation is dangling/unfinished). In any case, maybe ask in #codeql-community-packs on slack (the section in Contributing file should either be deleted or extended with the missing parts).
