[BUG] UWUFETCH_VERSION string not set in Github generated archives

[antecrescent]

Describe the bug
Github automatically creates source code archives which are commonly used by distros to fetch repositories at point releases.
These do not include the .git directory. Consequently, UWUFETCH_VERSION = $(shell git describe --tags) sets an empty string at compile time.

To Reproduce
Steps to reproduce the behavior:

1. Download https://github.com/github/TheDarkBug/uwufetch/refs/heads/main.tar.gz
2. Run make build
3. See described result in e.g. the cc flags.

Expected behavior
Sensible version string regardless of vcs presence in archive. I propose to hardcode the string and update it upon release of a new version. Another option would be to allow users to pass the string as a make argument but this doesn't seem correct to me.

Desktop (please complete the following information):

• OS: any
• Version since 2.0

Are you already working on this bug?
I want your feedback on my proposition before proceeding with my proposition.

Yes this is an issue I didn't think about, what solution would you propose?

[antecrescent]

Since UWUFETCH_VERSION only really has meaning at the release versions, I suggest hard-coding and incrementing it only upon release of a new version.

[ad-oliviero]

You are right, maybe a better solution would be to add compiler version and other compile-time info for debugging

[ad-oliviero]

I implemented a more complex way to "hard code" version tags. Now compiler info is included (for possible debugging purposes), git tag description and the version tag (hard coded as you suggested). Of course the bug will be actually fixed in the next release. I will close the issue before releasing 2.2 (or maybe 3.0, idk)
