chore: Use latest LS with the URL encoding fixes

[kittaakos]

Motivation

The Arduino language features must be functional when there is a # in the main sketch file name.

Change description

• Update the LS version with the fix,
• Removed an unused module from the code.

Other information

To verify:

• Your IDE2 installation contains a # in the path. The best is to use something like C:\Users\You\Desktop\# here is your IDE because it will ensure that after cutting the # (fragment) from the URI, it won't try to load VS Code extensions incorrectly from C:\Users\You\Desktop\.
• You have "arduino.language.realTimeDiagnostics": true, in the settings.json,
• Create a sketch with a # in the name or your sketchbook path has a #,
• Select a board,
• Make syntax errors,
• You see the error diagnostics in the editor.
• Create another .ino file and a .cpp lib in the sketch. The Arduino language features must be functional.
