Docs and `pyrefly suppress` use different spacing in ignore comments

[Aniketsy]

The docs show # pyrefly: ignore[bad-return] (no space), but pyrefly suppress generates # pyrefly: ignore [bad-return] (with a space).

Both forms work, but the docs never say the space is optional, so the mismatch looks confusing.

Suggested fix: maybe we can just add a note like this after

pyrefly/website/docs/error-suppressions.mdx

Line 90 in ed01fb5

This is equivalent to `pyrefly check --suppress-errors`.

The generated comments use the form `# pyrefly: ignore [error-code]`, with a space before
the bracket. This is equivalent to the `# pyrefly: ignore[error-code]` form shown above, and
Pyrefly accepts both.

happy to send a PR, if this looks correct or please let me know if it needs changes. Thanks :)

Good catch! I'm pretty sure we want to change the suppression script.

We should allow the space, but I don't think we want to encourage it, it looks kind of funny to me. The docs are the preferred style.

Assigning to you if you want to make a PR, feel free to unassign if you decide not to.
