Bump GOA

• What is the current behavior?

GOA was inconsistently being used @ V1.0.1 in the go.mod file. While GOA 2.0.0-WIP was used for the generation. For maintenance reasons, we decided to bump it to v3 and generate the code again. This requires bumping also the GO version used (see #814).

• What is the new behavior?

GOA is @ v3

• Does this PR introduce a breaking change?

It should not

• Other information:

Has to be rebases on main after #814 is merged ☑️
