fix: Update Home Assistant notification help text for HA 2024 Services→Actions rename

[Copilot]

Home Assistant renamed "Services" to "Actions" in 2024, making the notification configuration help text outdated and confusing.

Changes

• Field label: Notification Service → Notification Action
• Help text: Updated Developer Tools > Services → Developer Tools > Actions; added guidance that only the suffix after notify. should be entered (e.g. enter mobile_app_xyz, not notify.mobile_app_xyz); clarified that built-in mobile notifications require the action named "Send a notification via mobile_app_xyz", not "Send a notification" (which routes through external providers like Signal/Discord)
• Automation trigger example: call_service → call_action
• YAML snippet: service: → action:, service_data: → data:

# Before
domain: notify
service: mobile_app_my_phone
service_data:
  title: Uptime Kuma

# After
domain: notify
action: mobile_app_my_phone
data:
  title: Uptime Kuma

📝 Description

The Home Assistant notification copy is a bit out of date since HA renamed "Services" to "Actions":

A list of Notification Services can be found in Home Assistant under "Developer Tools > Services" search for "notification" to find your device/phone name.

It should read "Developer Tools > Actions" instead. The name of this field should probably be "Notification Action"

It could probably be good to also update this to be a bit more clear, it was confusing for me. Namely, make it more clear that the notify is omitted from the HA action name. Also note that for a built-in HA notification, you need the action noted "Send a notification via mobile_app_xyz" and NOT "Send a notification". The latter is for external notifications (Signal, Discord, etc), which a kuma user probably doesn't want to use through HA

@tr4nt0r could you maybe give the new wording a look over?
I have never used HA..

[tr4nt0r]

it's still call_service and service_data, that hasn't changed and the new location for the developer tools is Settings > Developer Tools > Actions

[CommanderStorm]

Thanks @tr4nt0r

@CommanderStorm I haven't contributed before, but shouldn't the translation key here (homeAssistantNotificationActionHelptext) be updated in all translation json documents? I think testing this in a non-english translation should happen.

Also the new key Notification Action

but shouldn't the translation key be updated in all translation json documents

No, this is intentional to not break our sync with weblate.
I don't speak all the languages we have, so we need to offload this to our awsome community of translators.

If you speak a non-english languages and want to improve our translations for that, we would be happy to have you -> https://weblate.kuma.pet/projects/uptime-kuma/uptime-kuma/
