bitwarden-cli docker image
this is based on the code in the external-secrets documentation.
both the Dockerfile and entrypoint.sh are a near-identical copy/paste.
the only change was to the Dockerfile to convert BW_CLI_VERSION from an ENV to an ARG,
so that the official upstream version can be read from the VERISON file for the ARG as well as the image tag
docker pull ghcr.io/charlesthomas/bitwarden-cli:<official bitwarden cli version>check VERSION to see what the actual value is.
when this doc was created it was 2023.12.1 so the full image was:
ghcr.io/charlesthomas/bitwarden-cli:2023.12.1
