Fix typo in code of conduct

[j-wags]

Description

I was reviewing the code of conduct and noticed that the contact emails were listed inconsistently. This aims to fix them and make them both valid email addresses.

Changes Made

Changed formatting of contact emails in code of conduct.

Type of Change

• Content Update
• New Content Addition
• Bug Fix
• Documentation Update
• Other (please describe):

Areas Affected

Code of conduct

Verification

• Content is accurate and up-to-date
• Changes follow existing formatting patterns
• Links have been tested (if applicable)
• No sensitive information included
  • I don't know if y'all would consider full-text valid emails sensitive (maybe that was the reason for the original formatting)
• Changes have been previewed locally

Additional Notes

I'm not particular about the final format of the email addresses in the code of conduct, this is just a drive-by PR and it's fine by me if this is closed and resolved some other way.
