Adding git to the Docker image

[mat813]

Is your feature request related to a problem? Please describe.

I would like to use the docker image in my Gitlab CI pipeline, like, adding a job that uses the docker image and runs:

$ graphql-inspector diff git:origin/main:./graphql/schema.graphql graphql/schema.graphql

But for this to work, the docker image needs git.

Describe the solution you'd like

Adding this to the second stage of the docker file would be enough:

RUN apk add -U git

It would add about 20MB to the generated image.

Describe alternatives you've considered

I can add the apk add -U git to my CI job, but it means hitting and downloading all the packages each time the job runs.
