Luke NaylorandPiotr Osiewicz 0ef19dedd2 Correct escaping in snippets (#14912)
## Release Notes:

- Fixed issue with backslashes not appearing in snippets
([#14721](https://github.com/zed-industries/zed/issues/14721)),
motivated by a snippet provided by the latex LSP
([texlab](https://github.com/latex-lsp/texlab)) not working as intended
in Zed ([extension
issue](https://github.com/rzukic/zed-latex/issues/5)).

[Screencast from 2024-07-21
14-57-19.webm](https://github.com/user-attachments/assets/3c95a987-16e5-4132-8c96-15553966d4ac)

## Fix details:

Only $, }, \ can be escaped by a backslash as per [LSP spec (under
grammar
section)](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/\#snippet_syntax).
Technically, commas and pipes can also be escaped only in "choice"
tabstops but it does not look like they are implemented in Zed yet.

## Additional tests added for cases currently not covered:
- backslash not being used to escape anything (so just a normal
backslash)
- backslash escaping a backslash (so that the second does not escape
what follows it)

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
