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

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.

Turn out this is the way gitbook deals with alt texts of images. We won't have to remove the badges just have to leave the alt texts empty if this is acceptable @smagdali
