chore(builder): add -DskipTests

[squakez]

We have no reason to try executing any test as we don't expect the presence of any test at all

The operator output is now the following one:

camel-k-operator-5f5bf4f7bb-2w2tz camel-k-operator {"level":"info","ts":"2024-05-31T09:27:58Z","logger":"camel-k.maven.build","msg":"--- maven-surefire-plugin:2.12.4:test (default-test) @ camel-k-integration ---"}

Release Note

chore(builder): add -DskipTests

@lburgazzoli do you think is this enough to solve the issue reported? It seems the execution of those mojos is skipped, but I am not sure if you were thinking in solving this problem differently. Do you mind having a look?

[lburgazzoli]

it probably won't impact our case but maven.test.skip is probably a better option

[squakez]

Change done. Execution is showing the following:
