Environment option keywords inside square brackets are not ignored (LaTeX)

[acarril]

Describe the bug
Environments with options in square brackets (e.g. \begin{frame}[noframenumbering]) are spell checked, but I think any options inside the brackets (i.e. noframenumbering) should be ignored. There doesn't seem to be a way to ignore the command using ltex.latex.commands or ltex.latex.environments.

Steps to reproduce
Steps to reproduce the behavior:

1. Create a frame environment and pass an option keyword which is not an actual word. For example, \begin{frame}[noframenumbering].
2. Verify that ltex doesn't ignore the environment option keyword:

Expected behavior
Option keywords in square brackets should be ignored.

Sample document
Minimal working example:

\documentclass{beamer}
\begin{document}
    \begin{frame}[noframenumbering]
        Foo
    \end{frame}
\end{document}

LTeX configuration
Please paste all configuration settings starting with ltex. from your settings.json. You can help us by temporarily removing some irrelevant settings from your settings.json and see if the bug still occurs.
