fix: ampersand sign rendered as & in bluesky

[mcleinn]

Ampersand (and) sign in X tweets is rendered as & a m p ; in Bluesky, both in web and Android client.

Also, I noticed that Hashtags (#remember at the beginning) is rendered as pure text in Bluesky (not clickable), but that is not a big problem, probably Bluesky does not have this functionality. It might still make sense to add this to a list of limitations in the docs.
