Andrew Duller created a script to ensure Git hooks were setup correctly. It is mentioned in README.git-hooks but it is not obvious to new developers that this should be read before working with the repo.

I propose that instead of adding to postStartCommand we update the main README with instructions for initial developer setup

I have added the script Andy wrote as a postCreateCommand to set up the githook infrastructure during container build. I also updated the README file.

Hi @JamesOHeaDLS, could this PR please be reviewed for approval once more? Given it's a minor tooling improvement.

Thanks @Ohisemega I can confirm that the config gets set on rebuild of the devcontainer
