Sam Thanawalla 77cfa29044 [release-branch.go1.21] cmd/go: download 1.X.0 instead of 1.X during toolchain upgrade.
This CL modifies the download behavior when downloading a toolchain for 1.21+. Previously, Go would attempt to download 1.X when upgrading the toolchain which would cause the download to fail for 1.21+ since 1.X is an invalid toolchain. We will attempt to download 1.X.0 since that's likely what the user intended.

Additionally, we will also now provide a better error message when the
user provides a language version instead of a toolchain version for
1.21+.

For #66175
For #62278

Fixes #67235
