GHA: main.yml: remove vezzal task

This task is failing due to invalid gmail email address or email outbound
MTA credentials via gmail, maybe the ${{secrets.MAILING_KEY}} is invalidated ?

While the docker image at vezzal/vezzal:v1 was last updated over 3y ago,
with vezzal/vezzal:v2 was last updated over 4y ago.

The project references a github upstream project that appears to be deleted
along with the entire user account associated with it.

https://hub.docker.com/r/vezzal/vezzal
https://github.com/lankasaicharan/vezzal

Because this does not appear to exist this now becomes a security concern
as the docker contents can not be audited as to what it does and it runs in the
context of the main project GHA CI that produces redistributable artifacts.

If this is be reinstated maybe it should be done as .github/workflows/vezzal.yml
so an independant workflow outside of the main.yml CI workflow that is used to
quickly cross check compilation state of the project.
