bug: Escaped `\$` counts as end of latex block

[ribru17]

Did you check existing issues?

• [X] I have read all the tree-sitter docs if it relates to using the parser
• [X] I have searched the existing issues

Tree-Sitter CLI Version, if relevant (output of tree-sitter --version)

tree-sitter 0.22.5

Describe the bug

Basically, escaped latex dollar signs are counted as ending delimiters, so it is basically impossible to have a regular dollar sign inside of an inline-equation latex block.

Steps To Reproduce/Bad Parse Tree

(inline [0, 0] - [1, 0]
  (latex_block [0, 0] - [0, 8]
    (latex_span_delimiter [0, 0] - [0, 1])
    (latex_span_delimiter [0, 7] - [0, 8])))

Expected Behavior/Parse Tree

(inline [0, 0] - [1, 0]
  (latex_block [0, 0] - [0, 14]
    (latex_span_delimiter [0, 0] - [0, 1])
    (latex_span_delimiter [0, 13] - [0, 14])))
