Fix flyway resource inclusion in native image when build is triggered from a Windows machine

[dquintela]

… from a windows machine

Testing with version 1.5.0.CR1 (also happening with 1.4.2.Final)

When triggering the native-build from the a windows machine, the included native resource has left slashes triggering the test in io.quarkus.flyway.runtime.graal.QuarkusPathLocationScanner#canHandleMigrationFile to fail and so native-image doesn't run any migrations.

Hi,

Thanks a lot for this PR!

The same fix has already been applied in #9531.
If we decide to merge that one, we can close this. If however we decide that we don't want that one, I'll go ahead and merge this PR.

Hi Georgios,

Thank you for the comment. Indeed, after I've opened the MR/PR, I noticed the same fix was applied there - that could have saved me some time..

But this is purely an hotfix and could be safely applied to 1.5 branch (master) and 1.4.x branch.

We most likely won't be doing any more 1.4.x releases, but you made a good point that this should be included in 1.5.0.Final, so lets merge now and I'll rebase my PR onto it.
