Fixed

• A Python version check is now performed before starting the language server to show human-readable error messages.
• Reduced LSP file events.
• Only glob for all builds if the main nRF Connect for VS Code extension isn't installed.
• Snippet insertions for boolean values with no valid options.
• Unicode symbols in files and the environment are now supported.
• The MODULE_EXT_DIR mechanism in west modules is now supported, which fixes issues with Kconfig symbols in some modules not discovered by the language server.
• Handling Windows URIs is now normalized to prevent formatting mismatches for build directories.
