Stacks Connect Page Formatting

[ginny-d]

This issue is about this page: https://docs.hiro.so/stacks/connect/packages/connect

Feedback:

• This page is very content-heavy. Headings could benefit from being one size up, as to not get lost in the paragraphs
• To keep consistency, remove the emojis from the titles
• We don't use titles on italics, instead it should read (*required) and not Required
