Trigger a GH workflow from searxng/searxng

[dalf]

Multiple PR in searxng/searxng change the theme. Usually, the PR descriptions contain multiple screenshots to describe the changes, but not scenarios are covered. It would be helpful if searxng/searxng could trigger this repository to build a report for each PR.

The trigger from searxng/searxng could be:

• either when the PR is opened
• or when there is specific comment inside the PR

Technically:

• Here: repository_dispatch
• searxng/searxng:
  • the use of Repository Dispatch
  • trigger:

on:
  pull_request:
    types:
      - opened
    paths:
      - 'searx/static/**'
      - 'searx/themes/**'

• alternative trigger: when there is a comment. So it is possible to call the bot multiple times (when the PR is updated).

The unsolved issue is the storage of the result (more than 700MB for each result).
Would it make sense to store them on a dedicated server? (for example the same VPS than searx.space, there are more than 30GB of available space).
