[Docker] Switch Docker Image to official php base image

[captn3m0]

Switches away from the unofficial Alpine+php image
to the official php-apache image. This has 2 advantages:

1. Official image is guaranteed to have regular updates etc
2. The persistent Docker Alpine DNS Issue goes away; DNS Issue gliderlabs/docker-alpine#255

[captn3m0]

This is testable by running the following:

docker create \
--name=rss-bridge \
--volume </path/to/whitelist.txt>:/app/public/whitelist.txt \
--publish 3000:80 \
captn3m0/rss-bridge:docker-improvements

Thanks for maintaining the Docker configuration 🥇

I just realized that the image size grew from ~35MB to ~190MB. Do you think that should be addressed?
I don't know if this is considered a "big" image or not.

It is definitely a bigger image, but I believe the advantages are worth it, in this case.

@logmanoriginal Just as a note, this changes the location of whitelist.txt on the container as well. If someone has a a custom list they were using along with this, it needs a slight change in the mount path. Adding the below to the next release CHANGELOG would be helpful:

The base docker image was switched from Alpine to the official PHP image. If you are using the Docker Image, note that the path to mount whitelist.txt has changed from /app/public/whitelist.txt to just /app/whitelist.txt. The wiki has been updated.

Thanks for updating the Wiki 👍
I added your message to the release notes for the next release.
