Sort images by tags

[evillique]

The sorting of the versions on the website is a bit random, this is an attempt to fix it

Hello! This invalid order of versions makes me unhappy too, but we cannot just sort tags in lexicographic order.

At least semver-friendly comparator should be used (splitting tags by '.' and comparing slices is enough), but I haven't yet come up with an idea of what to do with tags 'head', 'latest', and other non-semver tags.

It would be perfect if DockerHub provided us with the image tag creation date, but there is no such information (refer to the parsed dockerhub response).

I thought about hardcoding supported non-semver image tags (like 'latest', 'head', 'latest-alpine', 'head-alpine') and putting them at the beginning of the list of tags, but haven't yet decided if this is a good idea.

I made a new comparator, maybe it is a bit bulky, but overall it seems like it does the job: https://go.dev/play/p/Lm1PMLCsD3e

Implemented it in #21, thanks for the idea.
