fix typing in PL codebase - multiple PRs

[Borda]

🚀 Feature

add/fix typing in all PL codebase, this will yield in multiple PR as we prefer to split the work into smaller peace

Additional context

in #5021 we introduced a new ignore list so after it is merged, take out a single ignored item and fix typing for that part

each item + its fix = one PR

Great! Let me know (here or slack) which section you want to take (or you can take just position of a section and update ignore accordingly)

@Borda I'll just start in the order mentioned in the issue with callbacks. Let me know which sections @janhenriklambrechts has taken so I don't clash.
