Add internal integration “Month”

[Picholeiro]

Describe the feature

Proposal: Add internal integration “Month” that provides the name of the current month, similar to the “Seasons” integration.

Body of the Request

Use cases

Currently, users who need automations based on the month of the year (e.g., “turn on Christmas lights in December” or “change watering mode in summer”) must manually create complex Jinja2 templates or custom sensors.

Current workarounds

Although this can be obtained with {{ now().month }} in a template, there is no native, dedicated sensor entity that exposes this information in a standard way, with useful attributes, and that is detectable by the energy panel or entity selector in the UI.

Anything else?

Configuration: Like Season, it would be as simple as adding the integration from the interface, without the need for manual YAML configuration.

It would also facilitate programming in different languages, as people could make more automation features accessible in their different languages.
