Framework for supporting more languages in LanguageParser (#13318)
## 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
https://github.com/ThatsJustCheesy/langchain/pull/2)
  - Kotlin
  - Lua
  - Perl
  - Ruby
  - Rust
  - Scala
- TypeScript (contributed by @Harrolee
https://github.com/ThatsJustCheesy/langchain/pull/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
