Ignore user names mention in GitHub comments

**What problem does this solve?**
When you write "@asafm this looks great" it flags "asafm" as misspelled word.
Adding all usernames I work with to ignore seems too much.

**Proposed Solution**
Have it ignore "@{word}"

**Examples**
Gave above

Any other relevant info.

The issue names no files, tests, or entry points. Start by reproducing the example in a GitHub comment and trace where @word text is processed; done means usernames such as @asafm are ignored without suppressing genuine misspellings.
