get_many() no longer returns missing documents

[apetenchea]

get_many() was in a weird state:

• It would actually return the errors corresponding to missing documents, unlike the synchronous version of the driver
• The docs stated that it wouldn't

See #81

I think the best decision is to follow the docs and maintain compatibility with the old python-arango.
For that, I had to change the contract of get_many() and make it return Result[Jsons], meaning it can no longer return "Any" type (which would make filtering impossible).

Note

Medium Risk
Behavioral/contract change to get_many() can break callers relying on error entries or 1:1 input/output alignment; other changes are low-risk dependency and typing/tooling updates.

Overview
Changes Collection.get_many() to stop returning per-document error entries for missing/revision-mismatched documents. It now filters the API response to only include successful documents (those with _id) and tightens the return type to Result[Jsons]; tests are updated to expect shorter results instead of trailing error objects.

Bumps package/tooling versions and typing config: __version__ to 1.1.0, pyjwt minimum to 2.10.0, mypy to 1.15.0 (pre-commit and dev deps), and disables mypy’s warn_unused_ignores; adds a targeted # type: ignore[arg-type] for jwt.decode options.
