Simple typo in test paths generation.

[emonsler]

Describe the bug
The generated test path in two tests does not occur under the specified tmp_path.

To Reproduce
Run tests under test_delta.py.

Expected behavior
Test paths generated should be under the passed tmp_path.

OS, DeepDiff version and Python version (please complete the following information):

• DeepDiff Version 6.3.1

Additional context
There appears to be a simple typo, occurring twice.

deepdiff/tests/test_delta.py

Line 103 in 888ca77

path = os.path.join('tmp_path, delta_test2.delta')

deepdiff/tests/test_delta.py

Line 115 in 888ca77

path = os.path.join('tmp_path, delta_test2.delta')

path = os.path.join('tmp_path, delta_test2.delta')
should be
path = os.path.join(tmp_path, 'delta_test2.delta')
and
path = os.path.join(tmp_path, 'delta_test3.delta')

so that the delta_test?.delta leaf directories are under the provided tmp_path.
