Remove the deprecated badges and domain names in headings on programs page

[jochasinga]

This issue is two-fold but can be fixed in one go.

• Currently the deprecated badges are causing a formatting problem as seen attached. Since we organized them under "deprecated" section these badges are unnecessary anyway. We should remove them for readability.

• Some headings have parenthesized domain names trailing them, affecting readability and also causing unreadable URL slugs (i.e. #estuary-estuary.tech or #dataprograms.org-dataprograms.org). We should remove these domain names and if we really need to keep them add small "footnote" sections.
