ci: update pre-commit tools

[romanc]

Description

We haven't updated our linting tools in a long-ish time. In particular, isort was pointing to a repo that is archived by now. List of updates:

• black: 25.9.0 -> 26.5.1
• isort: 5.10.1 -> 8.0.1
• mypy: 1.18.2 -> 8.0.1
• yaml/toml formatter: 2.15.0 -> 2.16.0

How Has This Been Tested?

All good as long as CI is still green.

Not holding up this PR, but noting it here for posterity, we need to revisit the examples to make sure they are up to date.
