Dev mode no more working due to Flyway after migrating to 1.4

[loicmathieu]

Describe the bug
After migrating my project to 1.4.1.Final (or current master) from 1.3.1.Final dev mode didn't work anymore due to Flyway config issue.

Building and running the jar works fine.

Expected behavior
mvn clean quarkus:dev works fine.

Actual behavior
mvn clean quarkus:dev generates the following error and fails to start:

/cc @stuartwdouglas @mkouba does it ring a bell?

[stuartwdouglas]

Should be fixed by #8806

I did not realise the config bean changes had made it into 1.4, for some reason I thought they were in 1.5.

[loicmathieu]

Yes, #8806 fixed this.
