Update java grammar, including the addition of textblocks and fixes for the 'throws' and 'new' keywords

[hopehadfield]

Updating based on language-support/java/java.tmLanguage.json. The grammar is now owned there as per discussion at microsoft/vscode#187725 (comment).

The following changes are included:

• Added support for text blocks / triple quotes (Create Java grammar and add textblock highlight support vscode-java#3200 + Fix escape characters within textblock vscode-java#3412)
• Corrected comments after 'throws' keyword (Correct highlighting for comments after 'throws' vscode-java#3209)
• Fixed highlighting for 'new' keyword for inner classes (Fix highlighting on 'new' keyword for inner classes vscode-java#3224)

I don't think we should provide the grammar in eclipseide-jdtls any more. The TM4E project has https://github.com/eclipse/tm4e/tree/main/org.eclipse.tm4e.language_pack/java which does provide the grammar (which directly pulls from vscode repo). So instead of maintaining 2 copies, we'd rather remove textmate grammar from here and make com.redhat.eclipseide.jdtls bundle define a requirement on org.eclipse.tm4e.language_pack.

I've submitted #122 which does defer the issue to TM4E.

... https://github.com/eclipse/tm4e/tree/main/org.eclipse.tm4e.language_pack/java which does provide the grammar (which directly pulls from vscode repo).

... and VS Code now fetches from vscode-java 😉 (The original repo has been archived)

@hopehadfield , I would create a direct PR for updating the grammar in https://github.com/eclipse/tm4e and referencing how vscode-java became the main source.

I think TM4E does already fetch from VSCode. I think it's better to keep things simpler and stick to vscode, even if it causes a 1-month delay in the update.

Fair enough. They may just need a heads-up though. Last update was in 2022, https://github.com/eclipse/tm4e/commits/main/org.eclipse.tm4e.language_pack/java/java.tmLanguage.json .
