style: correct typos in comments and documentation (#13181) 
This PR fixes 15 spelling errors across 8 files in source comments,
docstrings,
and Lake CLI help text. No functional code changes.

Typos corrected: `auxillary` → `auxiliary`, `occurence`/`occuring` →
`occurrence`/`occurring`, `paramaters` → `parameters`, `precendence` →
`precedence`, `similiar` → `similar`, `contianing` → `containing`,
`specifed` → `specified`, `sythesized` → `synthesized`, `enviroment` →
`environment`. Also fixes grammar in `lake cache put` help text
(`used via be specified` → `used can be specified`, `Lake will used` →
`Lake will use`).

Files changed:
- `src/Lean/Elab/Coinductive.lean` — auxillary, occurence (×2),
paramaters
- `src/Lean/Server/FileWorker/SemanticHighlighting.lean` — precendence
(×2)

- `src/Lean/Meta/Tactic/Simp/Rewrite.lean` — sythesized
- `src/lake/Lake/CLI/Help.lean` — specifed (×2), grammar fixes
- `src/lake/Lake/CLI/Main.lean` — enviroment
