Copy link button in communities should generate the short URLs

Referring to the comment from @ori-near here: https://github.com/NEAR-DevHub/neardevhub-bos/issues/724#issuecomment-2237141973

If you click the "Share button" in a community, for example at https://devhub.near.page/community/protocol, you get the URL https://near.social/devhub.near/widget/app?page=community&handle=protocol.

You should get the URL: https://devhub.near.page/community/protocol

The same goes for community announcements and comments, and possibly more within the community.

See https://github.com/NEAR-DevHub/neardevhub-bos/pull/858 and https://github.com/NEAR-DevHub/neardevhub-bos/pull/868 to see how the same feature was solved for proposals.
