Kyle Kelley 557ca4ea79 repl: Support kernel language aliases in REPL (#49762)
Add a `kernel_language_names` field to `LanguageConfig` that allows
languages to declare alternative names that Jupyter kernels may use.
This fixes REPL matching for cases where a kernel reports a different
language identifier than Zed's language name.

For example, the Nu extension would set `kernel_language_names =
["nushell", "nu"]` in its config.toml, enabling REPL support for
nu-jupyter-kernel which reports `"language": "nushell"` in its
kernelspec.

The change consolidates kernel language matching logic into a single
`Language::matches_kernel_language()` method that checks the code fence
block name, language name, and the new aliases list (all
case-insensitive).

- [x] Done a self-review taking into account security and performance
aspects

Release Notes:

- Added `kernel_language_names` field for extensions to self identify
REPL mappings

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.
