[FR] upgrade shoutrrr to v0.8.0 to support custom fields in calls to Generic Webhooks

[huyz]

Is your feature request related to a problem? Please describe.

I have notifications sent to a Generic Webhook endpoint. But I'm in need of fields other than title and message to be sent.

Describe the solution you'd like

In order to support https://containrrr.dev/shoutrrr/dev/services/generic/#custom_data_fields , please bump the shoutrrr dependency to v0.8.0 to benefit from these commits: containrrr/shoutrrr#377

Describe alternatives you've considered

I current use hacks to inject data in the title and message fields and have to do special processing to extract that data.

Happy to merge and release a PR that updates this, in case anyone wants to do it.
