Update notice showing for v2.1.0 while already on v2.1.0

[kemitix]

After switching to the v2.1.0 docker image for woodpecker, the admin interface says to update to the current version.

This is from the docker image: woodpeckerci/woodpecker-server:v2.1.0

https://woodpecker-ci.org/version.json is having the v-prefix. So we either need to strip it when updating in ci or use string-replace in UI.

Similar in case of the woodpeckerci/woodpecker-server:next container:

But the "recommended" version doesn't exist!

I'll create a hotfix, and we should do semversion parsing wo compares versions

Thanks. Everything looks great now.
