Ibrahim Khan cbe92a9c1a snippets: Strip path separators from language snippet file names (#61421)
Closes #59620

## Problem

A language whose name contains a `/`, such as a custom `PL/X` extension
(`lsp_id` → `pl/x`), broke snippets end to end:

- The `snippets: configure snippets` action wrote the file to
`~/.config/zed/snippets/pl/x.json`, i.e. inside a `pl/` subdirectory.
- The snippet scanner reads `snippets/` non-recursively and skips
directories, so that file was never loaded and the snippet could never
be used.
- The completion lookup keyed off the raw `lsp_id` (`pl/x`), which
wouldn't have matched the file-stem key even if the file had been
scanned.

So Zed's own UI created a snippet file it could never read back.

## Fix

Add `LanguageName::snippet_scope_id()` (the `lsp_id` with `/` and `\`
removed) and use it everywhere a language maps to its snippet file name
or lookup key:

- the Configure Snippets writer and its "already configured" label, and
- the two completion lookups in `editor`.

`PL/X` now maps to a flat `plx.json`, as suggested in the issue. The
`editor::InsertSnippet` action is intentionally left unchanged: its
`language` field is documented to be the snippet file name stem, which
is already separator-free.

Note: files created under the old behavior (nested `foo/bar.json`)
aren't migrated; re-running Configure Snippets writes the corrected flat
file.

## Testing

- Added a `language_core` unit test asserting `snippet_scope_id()`
strips `/` and `\` (e.g. `PL/X` → `plx`).
- `cargo test -p language_core` passes.
- `./script/clippy -p language_core -p language` passes.
- Docs Prettier passes.

Release Notes:

- Fixed snippets being unusable for languages whose name contains a `/`

Licensing

Zed source code is licensed primarily under GPL-3.0-or-later, with Apache-2.0 components where marked.

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.
