chore: roll back remark dev dependencies to address failing release automation

[misteroneill]

Description

The release action has been failing for a while and it seems to be largely due to an update to some remark libraries. Rolling those back to the last known compatible versions.

Specific Changes proposed

• remark-cli goes from 11.x to 6.x
• remark-lint goes from 9.x to 6.x
• remark-parse goes from 10.x to 6.x

Requirements Checklist

• Feature implemented / Bug fixed
• Reviewed by Two Core Contributors
