feat(sterni/emacs): use bash login shell for M-x shell r/4053

bash (unlike fish) doesn't break down if TERM=dumb which is the only one
I'll be using in emacs (I want to reduce my usage of things depending on
ANSI escape sequence to a minimum, for stuff that needs it I still have
foot). bash is started in login shell mode so /etc/profile is sourced
which will a) enable direnv support and b) setup some tweaks (relating
to PAGER etc.) if TERM=dumb.

Since I use a semicolon for a prompt in (ba)sh, shell-prompt-pattern
needs to be adjusted.
