This commit adjusts the recommendation level for scripts that disable
UWP app access to accommodate user issues #121, #339, #350. It also
extends their documentation to reflect the new changes and with
cautions.
Changes:
- Add caution text for all scripts about potential impacts.
- Move disabling app access to notifications from 'Standard' to
'Strict'. This addresses #121 and #339, where users report lack of
notification as unintended side-effects.
- Move disabling app access to phone calls from 'Standard' to 'Strict'.
This addresses #350 where its effect on the Phone Link app was
reported as an unintended side-effect.
