KodiIdleTime: Remove surplus brace

[Mynacol]

This commit fixes a syntax error in the request sent to Kodi in the KodiIdleTime check. A sample request from autosuspend is following: {{"jsonrpc": "2.0", "id": 1, "method": "XBMC.GetInfoBooleans","params": {"booleans": ["System.IdleTime(300)"]}}

It has a surplus opening curly brace at the beginning, leading Kodi to ignore the request with the following log entry: error <general>: JSONRPC: Failed to parse [the above request]

This leads to the following exception in autosuspend:

autosuspend.Processor - WARNING - Check kodi-browsing[class=KodiIdleTime] failed. Ignoring... Traceback (most recent call last):
  File "/usr/lib/python3.11/site-packages/autosuspend/checks/kodi.py", line 93, in check
    if not reply["result"][f"System.IdleTime({self._idle_time})"]:
           ~~~~~^^^^^^^^^^
KeyError: 'result'

Thanks for the fix.

Before this can be merged, you need to reword your commit message to match the commit convention of the project. Could become something like "fix(kodi-idle-time): send proper requests"

Thanks for updating. Still a few things that wouldn't match the convention, but these are minor. The important part is the commit type in the first line as releases are based on the type of commit. I'll ignore the rest of the linting errors and merge this now.
