Merge pull request #61 from Burnett01/release/7.0.1

- Pin @JoshPiper [drinternet/rsync](https://github.com/JoshPiper/rsync-docker) image by SHA-256 hash rather than version.  (Immutability)
Added via #60 

The docker image of this action is now pinned to the specific SHA-256 hash of the version rather than just the version.
This means for the latest `drinternet/rsync:v1.4.4` the corresponding hash is `drinternet/rsync@sha256:15b2949838074bd93c49421c22380396a0cd53a322439e799ac87afcadcfe234`

Check for validation: https://hub.docker.com/layers/drinternet/rsync/v1.4.4/images/sha256-15b2949838074bd93c49421c22380396a0cd53a322439e799ac87afcadcfe234

With that, usage of this action is even more secure due to a consistent dependency chain of trust,
since changes accompanied by a docker image hash are immutable.

Thanks to @XComp
