💥 feat!: add tag filtering for projects (#431)

- Card (project) images no longer require manual top/bottom margin
adjustments for proper spacing. Action needed: Review existing card
images as previous manual margin adjustments may now be
unnecessary/excessive.
- Sites using `cards.html` with tags will now load JavaScript by
default when tags are present. To maintain no-JS behaviour, explicitly
set `enable_cards_tag_filtering = false` in either `config.toml` or the
`_index.md` file where `cards.html` is used.
