Issue with Autobuild for go 1.21.0 modules

Start with the reported go.mod version and the CodeQL autobuild logs, then inspect how the action selects and invokes Go tooling for module projects. Reproduce the failure with a Go 1.21.0 module and verify that autobuild and dependency extraction complete without the invalid-version error.

Hello! I'm not sure if this is the correct place to open this issue, but I recently updated my repo to the latest version of go (1.21). As per their release notes:

Go 1.21 introduces a small change to the numbering of releases. In the past, we used Go 1.N to refer to both the overall Go language version and release family as well as the first release in that family. Starting in Go 1.21, the first release is now Go 1.N.0. Today we are releasing both the Go 1.21 language and its initial implementation, the Go 1.21.0 release. These notes refer to “Go 1.21”; tools like go version will report “go1.21.0” (until you upgrade to Go 1.21.1). See “Go versions” in the “Go Toolchains” documentation for details about the new version numbering.

When updating modules now this new release numbering is used - see https://github.com/gilcrest/diygoapi/blob/main/go.mod

After updating to this, Autobuild on Github has the following errors.

Any help you can provide for this is much appreciated!
