Fixes with new ARM build instructions
```sh
# ARM 32 bit V6
- docker build -t qmcgaw/private-internet-access https://raw.githubusercontent.com/qdm12/private-internet-access-docker/master/Dockerfile.arm32v6
+ docker build -t qmcgaw/private-internet-access https://github.com/qdm12/private-internet-access-docker.git -f Dockerfile.arm32v6
# ARM 64 bit v8
- docker build -t qmcgaw/private-internet-access https://raw.githubusercontent.com/qdm12/private-internet-access-docker/master/Dockerfile.arm64v8
+ docker build -t qmcgaw/private-internet-access https://github.com/qdm12/private-internet-access-docker.git -f Dockerfile.arm64v8
```
I will rework the CI pipeline to build ARM images later.
