Tree-sitter

Currently, the lockfile only contains the commit hash of a parser. This is fine for the most part, but if we switch parsers for a language in parsers.lua, this will not be picked up by :TSUpdate, leading to a broken installation.

Instead, the lockfile should contain the full URL of the parser (repo and branch), and that should be checked (and kept updated via the CI action).

Tree-sitter states that it has "fairly complete" support for 34 languages with 12 more in development.

Right now this project states its support for 11 languages. Is there a way we can increase this number?

It would be an helpful addition to include the information provided by the highlight command besides Treesitter and Syntax if possible.
I get that currently with an extra function but perhaps it would be possible to integrate that in the TSHighlightCapturesUnderCursor popup?

Since I'm never sure whether I use the correct words and terms I've created a picture to clarify what I mean:
!

Here, the only word that should be marked is exampl:

\begin{titlingpage}
\textbf{This is an exampl:} \cite{somecitation}
\end{titlingpage}

Either add on to existing queries or add support for new languages. Relevant queries can be found using playground. See existing queries for examples (Rust is a good example).

(Elisp)-tree-sitter represents sections of the code it cannot parse as ERRORsymbol tokens. Currently the parser will fail as if a transformation is invalid if any ERROR tokens are present. Instead, we should check if the tokens in an operation contain ERROR, and alert the user that their code is malformed if so.
