Closes https://github.com/zed-industries/zed/issues/52242

This PR reverts a change that highlights shell script arguments as
variables rather than strings. Because of how shell scripts work, all
parameters are strings by default and are regularly represented as such.
The original PR (https://github.com/zed-industries/zed/pull/48067) aimed
to improve highlighting by capturing all arguments as
`variable.parameter`s, but this doesn't align with the idiomatic usage
of shell scripts.
