This is due the fact that Ansible often takes another default shell
to execute its commands, e.g., /bin/sh.
Solution is to require /bin/bash for the particular command.
In check_mode, the binary download task depends on the execution of the
previous one, which uses the module shell to fill in a variable. In the
download binary task we use a field on that variable that does not exist
in check_mode, so the task fails.

ANsible comes with the error:
```bash
[DEPRECATION WARNING]: evaluating gitea_fail2ban_enabled as a bare variable, this behaviour will go away and you might need to add |bool to the expression in the future. Also see CONDITIONAL_BARE_VARS configuration toggle.. This
feature will be removed in version 2.12. Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.
```
appending ``|bool`` after a boolean variable will resolve the issue.
Old behavior is to download the binary of `gitea_version` every run,
then checksum it against the currently installed version to see if it needs
to be copied over.
New behavior is to attempt to extract the current running version of gitea
and only initiate the old behavior if the running version != `gitea_version`.
Default is old behavior due to the major logic change involved.
