Some improvements to plugin initialization

[bdm-k]

Changes

• Fixed vulnerability in dependencies by running npm audit fix.
• Removed redundant sortSnippets calls in "main.ts". Snippets returned by the function parseSnippets are already sorted.
• Refactored the function refreshCMExtensions and renamed it to setEditorExtensions.
  • Moved the line calling this.app.workspace.updateOptions outside of the function so that its side effect is limited to modifying this.editorExtensions.
  • Eliminated the use of latexSuiteExtensions and optionalExtensions. The previous code feels hacky because it required @ts-ignore. In addition, I found the name latexSuiteExtensions unclear.
• Removed the call to reconfigureLatexSuiteConfig in processSettings. The extensions reconfigured by reconfigureLatexSuiteConfig will be removed in the call to refreshCMExtensions (setEditorExtensions in new code), so reconfigureLatexSuiteConfig is unnecessary.

The commit history has become a bit messy. Should I clean it up and force push?

[artisticat1]

Sure, go ahead.
