Resolve `E501` ignored Ruff rule

[kattni]

What is the problem or limitation you are having?

When Ruff was enabled, for review purposes, the identified errors were globally ignored, with the intention of resolving them in subsequent PRs.

Describe the solution you'd like

This repo currently ignores the following rules from the EXXX series:

• E501

Work through the issues as follows:

1. Comment out the error number in the ignore list found here.
2. Run pre-commit run -a to run the checks.
3. Work through each of the errors in the result until they are all resolved.
4. pre-commit run -a should pass without the errors in the ignore list.
5. Remove the E501 rule from the ignore list.
6. If this is the last of the errors in the ignore list, remove the ignore list completely, including the comment above.
7. Submit the PR.

Describe alternatives you've considered

None.

Additional context

The SIMXXX checks are explicitly disabled in the configuration. Do not remove the commented out SIM check, and avoid resolving the SIMXXX errors.

Hi, I am looking at this issue at EuroPython 2025 sprint weekend

[NMertsch]

For those looking into this:

black can fix some of these cases with the experimental string_processing feature:

black --enable-unstable-feature string_processing --preview --line-length 88 .

This will (among other things) splint long string at spaces, with the space at the beginning of the next line:

"Some long string"
" with spaces."

@freakboy3742 would prefer the space at the end of the previous line:

"Some long string "
"with spaces."

This can probably be done with a regex-replace.
