refactor: Updated Dockerfiles

[adriang-90]

• I have changed some issues that I have found with hadolint, like condense RUN commands, changed ADD with COPY nr 7.

• I also deleted some lines in RUN apk add --no-cache since it should be okay that way.

Looks like there's a CVE in the new images:

https://github.com/ory/hydra/runs/5788382665?check_suite_focus=true#step:10:37

So was that alpine:3.15.1 the problem? Hmmm that's strange because I did not changed it so how did it pass the tests so far?

Thank you! Sometimes CVEs get found and break builds at random times, but your fixes look perfect now! :)
