FIX: filter the std help ... by name, usage and search terms (#9035)

Browse Source 
Should close on of the points in
- https://github.com/nushell/nushell/issues/8813

# Description
this PR uses the new `--columns` option for `find` to filter the results
of the `std help` commands on the `usage`, `name` and `search_terms`
columns.

# User-Facing Changes
the `--find` option of `std help` commands should match more closely the
built-in `help` commands output.

# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- ⚫ `toolkit test`
- ⚫ `toolkit test stdlib`

# After Submitting
