github: change supported versions in different PR

[KaloyanTanev]

During the latest release there was an issue with the 2 PRs created from this pipeline. The first PR that bumped the v1.X-rc to v1.X in the main-v1.X branch did change the supported versions by adding the same, so it became:

var version = "v1.X" <--- changed in the same PR from "v1.X-rc"
...
func Supported() []SemVer {
	return []SemVer{
		{major: 1, minor: X}, <--- newly added line
		{major: 1, minor: X},
		{major: 1, minor: X-1},
...

Instead, we want this in the second PR that bumps v1.X-dev to v1.X+1-dev in the main branch, so that i becomes

var version = "v1.X+1-dev" <--- changed in the same PR from "v1.X-dev"
...
func Supported() []SemVer {
	return []SemVer{
		{major: 1, minor: X+1}, <--- newly added line
		{major: 1, minor: X},
		{major: 1, minor: X-1},
...
