Updated the version number of the Weather module from v2.3.1 to v2.3.2 in
the module metadata. This version increment likely corresponds to minor
bugfixes or improvements that have been implemented in the module. The
version change ensures proper tracking of module updates for users and
package management systems.
This commit corrects the hash key used to access device readings in the
Weather.pm module. All instances of the lowercase 'readings' hash key
have been changed to the uppercase 'READINGS', which is the standard
convention in FHEM. This fixes potential issues where weather data
wasn't being properly accessed or displayed because the module was
looking for readings in the wrong hash location. The change affects
the Get function and HTML rendering methods for both vertical and
horizontal layouts.
