Remove deprecated typing imports

[erlingstaff]

Description

Several imports from typing are deprecated, and should be either:

1. Removed in favor of builtins, ex: typing.Dict -> dict
2. Re-imported from another module, ex: from typing import Callable ->
   from collections.abc import Callable

The deprecations are relevant in Python versions ranging from 3.8 -> 3.12. This issue focuses on the imports deprecated in 3.8 or 3.9, as 3.9 is the minimum Python needed to run Rucio (as outlined in setup_rucio.py). When Rucio is updated, there might be new deprecations.

The following grep command finds all (i think) instances of deprecated imports:

grep -R --include="*.py" -E "from typing import.*(Callable|Iterator|Iterable|Sequence|AbstractSet|Dict|Tuple|List|Set|Type|FrozenSet|Tuple|DefaultDict|OrderedDict|ChainMap|Counter|Deque|AbstractSet|Collection|Container|ItemsView|KeysView|Mapping|MappingView|MutableMapping|MutableSet|MutableSequence|ValuesView|Corutine|AsyncGenerator|AsyncIterable|AsyncIterator|Awaitable|Generator|Reversible|ContextManager|AsyncContextManager|Match|Pattern)(,| )" .

This currently returns

Motivation

1. Standardize imports
2. Avoid DeprecationWarnings and larger changes in the future

Change

1. Find all deprecated imports from typing, either manually or automatically using e.g. the aforementioned grep command
2. Change as appropriate

We’ve already had #6276 and I’m guessing that they may be accidentally reintroduced again in the future. Could you investigate the use of Ruff?

Good catch on Ruff having this functionality - I'm configuring Ruff to include a few more features, I'll assign this issue to myself to look into adding this too
