Option to Define Target Version

Is your feature request related to a problem? Please describe.
Updating to the most recent release is potentially not always desired.

Describe the solution you'd like
I think it would be nice to have a CLI option that allows to install a specific version by version tag. This could look like the following to install version 1.13.6 instead of 1.14.1, which is as of now the latest release:

gitea-auto-update -v 1.13.6

Or maybe even pinning to a minor version, where the following would install the latest bug-fix release of 1.13:

gitea-auto-update -v 1.13

Describe alternatives you've considered
Do not see any.

Additional context
None.

Well, the whole idea behind this project was upgrading to the latest version because older versions can have security issues.

I get your point (maybe a newer version has breaking changes or introduces new bugs), but I am not sure if I will implement this.
