I loaded a NestJs backend repo with this parser and have had MUCH better results with RAG QA than with the GitLoader.

Thank you! We will make sure to credit you for this in the main Langchain PR.

(We've implemented this for an ongoing school project, so that's why it's sat for so long. Design document)

## Description

I am submitting this for a school project as part of a team of 5. Other
team members are @LeilaChr, @maazh10, @Megabear137, @jelalalamy. This PR
also has contributions from community members @Harrolee and @Mario928.

Initial context is in the issue we opened (#11229).

This pull request adds:

- Generic framework for expanding the languages that `LanguageParser`
can handle, using the
[tree-sitter](https://github.com/tree-sitter/py-tree-sitter#py-tree-sitter)
parsing library and existing language-specific parsers written for it
- Support for the following additional languages in `LanguageParser`:
  - C
  - C++
  - C#
  - Go
- Java (contributed by @Mario928
ThatsJustCheesy#2)
  - Kotlin
  - Lua
  - Perl
  - Ruby
  - Rust
  - Scala
- TypeScript (contributed by @Harrolee
ThatsJustCheesy#1)

Here is the [design
document](https://docs.google.com/document/d/17dB14cKCWAaiTeSeBtxHpoVPGKrsPye8W0o_WClz2kk)
if curious, but no need to read it.

## Issues

- Closes #11229
- Closes #10996
- Closes #8405

## Dependencies

`tree_sitter` and `tree_sitter_languages` on PyPI. We have tried to add
these as optional dependencies.

## Documentation

We have updated the list of supported languages, and also added a
section to `source_code.ipynb` detailing how to add support for
additional languages using our framework.

## Maintainer

- @hwchase17 (previously reviewed
#6486)

## Git commits

We will gladly squash any/all of our commits (esp merge commits) if
necessary. Let us know if this is desirable, or if you will be
squash-merging anyway.
