add alarms-list output formats

[DhruvaSambrani]

Adds --format and --json to list alarms. Semi-fixes #148, actual alarm implementation can be done externally.

I am unable to see the failure of pre-commit.ci, I only see Internal Service error sent as json (??). Is this temporary or am I missing smthing?

Interesting; it works with uBlock Origin for me; maybe something is interfering with full networking? Anyways, here is the output:

@DhruvaSambrani sounds like a temporary glitch. You can also run these checks with pre-commit run locally.

I can fix it either by typing the attributes dict explicitly, or serialize json to keep the same type.

If I change the type to dict[str, Union[str, list[dict[str, object]]]], it adds an error on line 694

khal/khalendar/event.py:694: error: No overload variant of "__add__" of "list" matches argument type "str"  [operator]
khal/khalendar/event.py:694: note: Possible overload variants:
khal/khalendar/event.py:694: note:     def __add__(self, list[dict[str, object]], /) -> list[dict[str, object]]
khal/khalendar/event.py:694: note:     def [_S] __add__(self, list[_S], /) -> list[_S | dict[str, object]]
khal/khalendar/event.py:694: note: Left operand is of type "str | list[dict[str, object]]"
khal/khalendar/event.py:694: error: Unsupported operand types for + ("str" and "list[dict[str, object]]")  [operator]
khal/khalendar/event.py:694: note: Both left and right operands are unions

This can also be fixed by typing it as dict[str, Any], but maybe that is too generically typed?

The other way is to use a TypedDict, but that seems too complicated for a pre-ci fix.
