Update code to use the latest lsp4ij from Microshed

[turkeylurkey]

There is an lsp4ij branch on Microshed that uses the lsp4ij code from 11/01.

Update this tool to make use of that. This mainly affects the MicroProfile support (e.g. lsp4mp4ij) but these changes will also affect the other language servers.

Issues required to close this item:

• MicroProfile snippets are not context aware #431
• Integrate newest LSP4Jakarta release when available #521
• Custom config dir/files support does not initialize on IDE startup or opening project #535
• Use the same Lemminx version as LCLS #587
• Track issue in LCLS concerning error message severity #603
• Warning diagnostic appears on properties in bootstrap.properties #604
• Regression tests required for latest lsp4mp4ij code merge #605
• Investigate whether the properties file update bug has been fixed #606
• ProcessCanceledException while processing MicroProfile diagnostics #612
• Fail to account for prefix during completion in properties file #622
• server.xml element validation error in test #623
• Invalid completion items appear in server.xml #624
• Error starting server in automated test #625
• Apply catch/rethrow IndexNotReadyException, ProcessCanceledException and CancellationException to recent LSP4Jakarta integration. #634
• Quick fixes are not reliably made available to the user the first time they hover over a diagnostic. #644
• Diagnostics are not always published when a file containing an error is opened. #648
• Enable automated UI tests for MicroProfile completion. #654
• Enable automated UI tests for all language server quick fixes. #653 (try after resolving Quick fixes are not reliably made available to the user the first time they hover over a diagnostic. #644)
• Update to latest LCLS release when available #620
• Support IntelliJ IDEA 2023.3 #590
• Review the descriptions of the language servers #671
• Update the documentation and release notes for 24.0.3 #679

This issue is to be marked complete only when the useLSP4IJ1201 feature branch has been merged into main.

After merging, we should check old "language client" bugs to see if the LSP4IJ update has resolved them or not. (Incomplete - work item open to address later: #732)

After merging the latest lsp4mp4ij code and the MicroProfile client code

1. the MicroProfile support produces diagnostics and completion
2. The Jakarta diagnostics only appear if you perform some other action in the Java file like hover or completion.
3. The LCLS diagnostics appear in bootstrap.properties after you perform hover or completion.
4. The lemminx diagnostics do appear when you open server.xml.

ToDo:

• start Jakarta language server when a Java file is opened
• start the LCLS language server when a properties file is opened
• start the lemminx server when an XML file is opened

Liberty Config
XML:

• diagnostics
• xml completion
• feature completion in server.xml
• hover

Properties:

• diagnostics for invalid values are not displayed (It is handled without underline, only hover text. Opened [properties] Specify a severity for diagnostics related to a properties file. liberty-language-server#260 to track this.)
• invalid diagnostic "Unknown property 'default.http.port'" Caused by lsp4mp, more analysis needed.
• hover
• completion
