oca-checks-po: po-pretty-format - Verbose "Wrong formatting"

[moylop260]

Is your feature request related to a problem?

If you enable oca-checks-po hooks with po-pretty-format check enabled but without --fix arg it shows only:
Wrong formatting but it doesn't show the diff or something to know where it is wrong

Describe the solution you'd like
Show the diff from original po file with the changes

Describe alternatives you've considered

It should shows the diff from the both variables sources:

• odoo-pre-commit-hooks/src/oca_pre_commit_hooks/checks_odoo_module_po.py

  Line 101 in 3695cf4

  if self.pretty_contents != self.original_contents:

Related to OCA/server-env#204

Agree, the error is not meaningful.

The pre-commit has this feature

I mean, it is showing the diff if fails with the following parameter --show-diff-on-failure

And it is enabled in the CI pre-commit for the OCA:

• https://github.com/OCA/server-env/blob/c7a112b5055994f43e9a75c2fe37417cbe1fc068/.github/workflows/pre-commit.yml#L29

IMHO we could duplicate the feature to show the diff when it is covered from pre-commit

So, closing it since that we could dedicate our efforts to another feature
