README.md in "base" contains incorrect crontab example, docker-compose example outdated

[JulesCornelissen]

The crontab.txt example found here does not match the crontab.txt file found in the same folder. Using the example found in the README.md file results in the following error:

Using the file supplied in the folder resolves the issue.

Furthermore, the README.md file notes that /root/.borgmatic: Note this is now redundant and has been deprecated, please remove this from your configs. However, this mount point is still included in docker-compose.yml.

And on a final note, thanks for creating and maintaining this project!
