Update Deployment Comment

[lkiesow]

Instead of writing a new comment every time the static test site gets deployed, this patch will cause the first comment to be updated similar to the container image deployment.

This means that if you open a pull requests, the first two comments should usually hold all information about the latest deployment.

Use docker or podman to test this pull request locally.

Run test server using develop.opencast.org as backend:

podman run --rm -it -p 127.0.0.1:3000:3000 ghcr.io/opencast/opencast-admin-interface:pr-579

Specify a different backend like stable.opencast.org:

podman run --rm -it -p 127.0.0.1:3000:3000 -e PROXY_TARGET=https://stable.opencast.org ghcr.io/opencast/opencast-admin-interface:pr-579

It may take a few seconds for the interface to spin up.
It will then be available at http://127.0.0.1:3000.
For more options you can pass on to the proxy, take a look at the README.md.

I don't know if this is working every time. But let's merge it anyway and see if it does anything...
