bash: revert automatic shell integration changes

Browse Source 
The intention of #5075 was to create a less intrusive, more hermetic
environment in which to source the bash startup files. This caused
problems for multiple people, and I believe that's because the general
expectation is that these files are sourced at global (not function)
scope.

For example, when a file is sourced from within a function scope, any
variables that weren't explicitly exported into the global environment
won't be available outside of the scope of the function. Most system and
personal startup files aren't written with that constraint because it's
not how bash itself loads these files.

As a small improvement over the original code, `rcfile` has been renamed
to `__ghostty_rcfile`. Avoiding leaking this variable while sourcing
these files was a goal of #5075, and prefixing it make it much less of a
potential issue.

This change also reverts the $HOME to ~/ change. While the ~/ notation
is more concise, using $HOME is more common and easier to implement
safely with regard to quoting.
