feat: add go 1.25 and go 1.26

[mitchellkalika]

Adds the two most recently released golang versions to the build list

From #36 - you can work around this in the short term by adding the below env var to your deployment to update the toolchain version

    devImage: ghcr.io/loft-sh/devspace-containers/go:1.23-alpine
    env:
      - name: GOTOOLCHAIN
        value: go1.24.0

Plus 1 to this. It'd be nice to have new containers: Golang 1.24 has already reached its EoL.

@lizardruss any chance you can take a look? 🙏

@lizardruss @loft-sh — bumping this again. Go 1.24 has already reached EoL and 1.25/1.26 are out. This PR is a straightforward matrix addition with no risk. Would be great to get it merged. 🙏
