fix(linux): Use first keyboard language if none given 🍒

fix(web): Fix layers for embedded longpress keys

Co-authored-by: Joshua Horton <joshua_horton@sil.org>

This fixes a bug introduced in #3290 where we added using the
language from search. Unfortunately that broke things in a lot of
other places because we didn't test for the empty string.

(cherry picked from commit fe0e4234)

chore: fixup stable HISTORY.md 🍒 🏰

On local builds we shouldn't upload errors to Sentry. The
`build-utils.sh` script sets the `UPLOAD_SENTRY` environment variable
for that purpose. Also, Sentry doesn't like having an empty string
as pkgversion (which should no longer happen with the rest of this
change, but...)

- allow to specify distribution
