Use groups to have a standard output

[gagoar]

currently we have either DEBUG flag or no logs at all.

DEBUG is useful to understand exactly what's happening, but in most cases is too noisy.

We should have a normal log output that offers information everybody will be happy to see.

we should use for this startGroup and endGroup from actions/core
example:

core.startGroup('Do some function')
doSomeFunction()
core.endGroup()
