Fix grammatical errors throughout the documentation (#58183)

Fixes a batch of grammatical mistakes found across the `docs/` folder:
typos/misspellings, subject-verb agreement errors, missing and
duplicated words, article errors (`a`/`an`), wrong word forms, and
punctuation issues (doubled periods, unclosed parentheses).

Scope is limited to prose in `docs/src/**`; no behavior, settings, or
code changes. 33 files updated, 49 lines changed.

Representative fixes:

- `globs.md`: "features varies" -> "features"; "platforms libc" ->
"platform's libc".
- `installation.md`: "the follow macOS releases" -> "the following macOS
releases".
- `key-bindings.md`: "command pallets" -> "command palette's".
- `linux.md`: capitalization after a period; "able to the environment
variable" -> "able to set the environment variable"; "These feature also
requires" -> "This feature also requires".
- `multibuffers.md`: "Window/Linux" -> "Windows/Linux"; added a missing
closing parenthesis.
- `reference/all-settings.md`: several agreement/article/missing-word
fixes plus an unclosed parenthesis.
- `languages/*`: "partent" -> "parent", "complimentary" ->
"complementary", "setup" -> "set up", "is enabled" -> "are enabled", and
similar.

Release Notes:

 ### LuaCATS Definitions
 
-LuaLS can provide enhanced LSP autocompletion suggestions and type validation with the help of LuaCATS (Lua Comment and Type System) definitions. These definitions are available for many common Lua libraries, and local paths containing them can be specified via `workspace.library` in `luarc.json`. You can do this via relative paths if you checkout your definitions into the same partent directory of your project (`../playdate-luacats`, `../love2d`, etc). Alternatively you can create submodule(s) inside your project for each LuaCATS definition repo.
