Add more commands for automatic vowel detection in formulas

[scaomath]

Related to valentjn/vscode-ltex#131.

Background

I write papers which constantly uses an $\alpha$-weighted interpolation and an $\widetilde{H}^1$-conforming space. One day I was too tired at night, fixing typos relying on LTeX (but telling me collaborators I was working hard), and did not manually check the things. The final version almost got to the publication stage...

Change

Basically added more LaTeX commands in the following block:

ltex-ls/src/main/java/org/bsplines/ltexls/parsing/latex/LatexAnnotatedTextBuilder.java

Lines 625 to 633 in 287b8e0

	if (isMathMode(this.curMode) && (this.mathVowelState == MathVowelState.UNDECIDED)) {
	if (command.equals("\\mathbb") || command.equals("\\mathbf")
	|| command.equals("\\mathcal") || command.equals("\\mathfrak")
	|| command.equals("\\mathit") || command.equals("\\mathnormal")
	|| command.equals("\\mathsf") || command.equals("\\mathtt")) {
	// leave this.mathVowelState as MathVowelState.UNDECIDED
	} else if (command.equals("\\ell")) {
	this.mathVowelState = MathVowelState.STARTS_WITH_VOWEL;
	} else {

• Added some commonly used Greek letters such as \alpha, \epsilon, etc;
• Added some commonly used amsmath commands such as \operatorname{}, \mathop{}, and tildes and hats.

Thanks for the pull request. Sorry to hear you almost got some typos published. Of course, a grammar/spell checker doesn't replace the manual proofreading stage, even if the checker is as great as LT_EX. Maybe I should add a disclaimer somewhere.
