Update Prom2teams image

[jthiatt]

Hi friends,

This is a great project I would like to use it.
I have a (hopefully) simple ask below.

Description

Prom2teams container fails image scans, lots of high vulnerabilities found.
Updating the base image seems to resolve these issues, is there a way that this project could be built more often?

Why is this needed?

Good security hygiene
