release.sh: identify the remote before switching into DRYRUN mode (#…

…1498)

Motivation:

Current version of the release script identifies the remote after the
`DRYRUN` mode overrides `git` command. As the result, logs do not show
which remote will be used when the `DRYRUN` mode will be off.

Modifications:

- Move lines that identify `remote` before the `DRYRUN` mode check;
- Print a message when `DRYRUN` mode is enabled;

Result:

`DRYRUN` mode correctly shows the git remote.
