we only care about patch versions

[dprotaso]

Dependabot bumped our 1.19 image to 1.20 which is something we don't want.

I'm hoping this change will mean we'll only bump respective patches

Do you have a link to the unwanted bump? I see 1305d23 this is most recent 1.19->1.20

[krsna-m]

initial behavior was to have a latest stable go version and manually bump older versions https://github.com/knative/test-infra/pull/3746/files#diff-3a809bc2ddb42dd8cd4627d729d61452cc1ed660a8d82ae02476cf740e7740faR242

1305d23 this broke that assumption.

I see the logic you want to implement though.
