Currently long-form comments in the activity feed are truncated in three different ways...
- Comment on issue/PR: to 200 characters, with an ellipsis, potentially splitting the middle of multi-line markdown blocks
- PR review: first line of text in the review comment
- PR review dismissed: no truncation on comment text...
- Although this feed entry doesn't work currently (#8853) and the UI doesn't really lend itself to long comments anyway.
For the sake of consistency, and to fix#8781, this PR fixes the implementation so that all truncation occurs by grabbing the first line of text and then truncating it to 200 characters if necessary.
This fixes#8781 by not ever truncating in the middle of a markdown *block*; it's still possible to trigger some unexpected behavior such as:
- Truncate in the middle of markdown structures like a link, causing raw markdown to render in the feed
- Provide an image embed on the first line of a comment, causing an image to appear in the feed; if it's a large image it could disrupt browsing a nice brief activity feed
But these behaviors seem acceptable edge cases until they're identified to cause any significant user impact.

- Adds a new option `[webhook].PAYLOAD_COMMIT_LIMIT` that limits the amount of commits is sent for each webhook payload, this was previously done via `[ui].FEED_MAX_COMMIT_NUM` which feels incorrect.
- The default is 15 for this new option, purely arbitary.
- Resolvesforgejo/forgejo#6780
- Added unit testing, it's quite a lot because this the notification
area is not really easy to test and rather should've been a integration test
but that ends up having more complicated than trying doing an unit test.

- Make use of `test.MockVariableValue` to override variables for the
duration of the test.
- Don't needlessly call `onGiteaRun`, its only needed when a HTTP server
needs to be called by the code.
- When `onGiteaRun` is used, make use of the passed parameters, such as
the passed `*testing.T` variable and `*url.URL` (this also avoids
needing to serve the routers in the test code again).
- Use `(*url.URL).JoinPath` to craft new URLs.
- Don't override `setting.AppURL` & `setting.Database.LogSQL` when its
does not affect the test.
- Add empty fixture files for `FederatedUser` & `FederationHost` so they
are truncated and do not persist between tests.
This PR removed `unittest.MainTest` the second parameter
`TestOptions.GiteaRoot`. Now it detects the root directory by current
working directory.
