This enables some ruff rules to check for ambiguous and dead Python
code, which might cause unintended side-effects.
The enabled rules are:
- a bunch of rules related to shadowing of builtin structures (A)
- a bunch of rules checking for unused arguments (ARG)
- a rule checking for useless expressions (B018)
- a rule checking for unbound loop variables (B023)
- a rule checking redefined function parameters (PLR1704)
This updates shell scripts to use a consistent style that can be enforced
via pre-commit hook.
As for choosing tabs over spaces, some arguments are:
- tabs can help people with visual impairment
- tabs allow for indenting heredocs in bash
- tabs are the default for the tool shfmt

In the ruff config file added in #6954 explicitly selecting the ruff
rules to check was missed, resulting in ruff only checking a very small
subset of its available rules. That hasn't been desired, so this is the
first of a series of commits enabling more rules. In this PR all rules
whose violations can be either automatically fixed by ruff or are
trivial to fix manually get enabled. For the follow up PRs it's intended
to focus on one area of rules per PR to gradually improve the Python
code quality.
