Turning Search field in blocks into filters

[SimoneZaza]

Description

As a user, I don't like the filter chips stacking on top of each other in the search input. Also, I like to get direct feedback when I'm typing. A filter field instead of a search field seems more fit for purpose in these blocks.

Acceptance criteria

• [ ] Keep current styling, but use the behavior of the filter component (as on Contributors page) instead of search component in search fields inside blocks:
• [ ] Both blocks on Innovation library: https://alkem.io/innovation-library
• [ ] Spaces search block on Spaces page: https://alkem.io/spaces
• [ ] Subspaces block in Space on Subspaces tab: eg https://alkem.io/building-alkemio-org/challenges
• [ ] Contributors block in Space on Community tab: eg https://alkem.io/building-alkemio-org/community
• [ ] NB the results should be complete, not just a filter on what is currently visible because of pagination. It is okay if this is loaded in chunks, and not all visible directly if there is a loading indication.
