[CLI] Better CLI errors formatting (#3889)
* Better CLI errors
* Fix label capitalization consistency: lowercase when mid-sentence
In _format_entry_not_found, the label appeared mid-sentence ('File not
found in Dataset ...') but was capitalized. Apply the rule consistently:
capitalize when starting a sentence, lowercase otherwise.
Update tests to match the corrected casing.

* Fix mypy errors: make _format() generic to preserve subclass types
Use TypeVar to make _format() return the specific HfHubHTTPError
subclass type, so mypy recognizes attributes like repo_type, repo_id,
and bucket_id on the returned error objects.

* Fix mypy: use distinct variable names per error branch in hf_raise_for_status
Mypy narrows the type of 'err' on the first assignment and then
rejects reassignments to different subclass types in later elif
branches. Use unique names (revision_err, entry_err, gated_err,
bucket_err, repo_err) to avoid cross-branch type conflicts.
