Documentation suggestion: Remove "(1)" from web tabs

[eriksjolund]

This is just a minor annoyance.

When I have opened a documentation page such as
https://docs.podman.io/en/latest/markdown/podman-run.1.html
I often get fooled that there is some update available because
the web browser tab displays "podman-run (1)".

In different web sites I've seen (1) as being used as an indication that updates are available, for instance in GitHub issues.

podman/docs/source/conf.py

Line 75 in f4d6e87

source[0] = re.sub(r"^% (.*)", r"```{title} \g<1>\n```", source[0])

I think you would need to change this line.
