Configuration fails if git is not on path

[isc-tleavitt]

Error log:

NAMESPACE>do ##class(SourceControl.Git.API).Configure()
Configured SourceControl.Git.Extension as source control class for namespace CPM
Configured default mappings for classes, routines, and include files. You can cu
stomize these in the global:
     ^SYS("SourceControl","Git","settings","mappings")
WARNING: You are using an older version of git which is not compatible with git-
source-control. Please upgrade to git version 2.31.0 or greater to continue
Cancelling git-source-control configuration...

Intuitively I think the issue is:

        set gitExists = ##class(SourceControl.Git.Utils).GitBinExists(.version) // version is "", gitExists = 0
        set gitBinPath = ##class(SourceControl.Git.Utils).GitBinPath(.isDefault)

        // Make sure they are using an appropriate git version
        if (+$PIECE(version,"version ",2))<2.31 { //0 < 2.31
            write !!, "WARNING: You are using an older version of git which is not compatible with git-source-control. Please upgrade to git version 2.31.0 or greater to continue"
            write !!, "Cancelling git-source-control configuration..."
            quit
        }

We shouldn't do the version check if gitExists is false.

Simple solution (worked on customer call) is:
if (+$PIECE(version,"version ",2))<2.31 && gitExists {

But this is still kind of silly - it would be better to repeat the version check after configuration and cancel configuration if things are still going to be broken.
