Makes use of a pre-push hook to bump version numbers

[adammccartney]

Description

We're currently manually bumping version numbers in the following files every time we prepare for a tagged release.

       modified:   Charts/pacman/Chart.yaml
        modified:   Documentation/localdev.md
        modified:   deployments/pacman-deployment.yaml
        modified:   localdev/docker-compose.yml

Solution

A simple script to check that the versions match the tag before we push.
