Remove older Juju compatibility code

[dimaqq]

Specifically:

data-platform-libs/lib/charms/data_platform_libs/v0/data_interfaces.py

Lines 911 to 921 in a597e8e

	try:
	self._secret_content = self.meta.get_content(refresh=True)
	except (ValueError, ModelError) as err:
	# https://bugs.launchpad.net/juju/+bug/2042596
	# Only triggered when 'refresh' is set
	if isinstance(err, ModelError) and not any(
	msg in str(err) for msg in self.KNOWN_MODEL_ERRORS
	):
	raise
	# Due to: ValueError: Secret owner cannot use refresh=True
	self._secret_content = self.meta.get_content()

I believe this has been fixed already:
https://bugs.launchpad.net/juju/+bug/2042596
https://bugs.launchpad.net/juju/+bug/2037120

In which case, the only affected Juju versions were 3.0.x and older 3.1.x;
Now that those minor versions are EOL, the work-around can be removed.
