feat: rename output binary and archives

Update the goreleaser config to rename the output binary and archive names
to `fail2ban_exporter` instead of defaulting to the project name. This
better aligns with conventions used by other exporters.
Update Dockerfile and Makefile to follow the new naming scheme.
Update the output archives to wrap the build files in a folder. This makes
extracting the archives a little easier.

BREAKING CHANGE: Release binary name has been changed to `fail2ban_exporter`.
