Change color of github tag and homebrew badges to blue

Both of these badges have the coloring logic to show stable releases in blue,
and prereleases in orange. The criterion for a prerelease is that the major
version is 0. Now it is debatable whether we consider lazygit "stable", but I
don't feel we are in a preliminary state of the project, working towards the
first final 1.0 release, so I feel blue expresses the state of the project
better.
