Use registry_path checker from pephubclient

[khoroshevskyi]

I added registry path checker to pephubclient, so now we should use this function from pephubclient.
How to use it:

from pephubclient.helpers import is_registry_path
is_registry_path(sample_pep)

Sounds like that function belongs in ubiquerg.

There's already parse_registry_path there: https://github.com/pepkit/ubiquerg/blob/bbca867a7c3581bad51723977db3791d999d8591/ubiquerg/paths.py#L21

as long as there are no dependencies

This is the current implementation in looper utils, it uses both ubiquerg and pephubclient to determine if input path is a registry path to pephub:

from ubiquerg import convert_value, expandpath, parse_registry_path
from pephubclient.constants import RegistryPath

looper/looper/utils.py

Lines 565 to 569 in 2675eef

	try:
	registry_path = RegistryPath(**parse_registry_path(input_string))
	except (ValidationError, TypeError):
	return False
	return True

Closing this in favor of: pepkit/ubiquerg#43 and #456
