CI broken

[forman]

Describe the bug

CI tests currently fail presumably caused by dependency updates:

=========================== short test summary info ============================
FAILED tests/config/test_validate.py::ConfigValidateTest::test_validate_variable_fail - AssertionError: Regex pattern did not match.
 Regex: "Invalid configuration: 10 is not of type 'string' for variables.chl.dims.0"
 Input: "Invalid configuration: 30 is not of type 'string' for variables.chl.dims.2"
FAILED tests/test_xrencoding.py::XArrayEncodingTest::test_overlapping_chunks_in_data_and_encoding_raises - ValueError: Specified zarr chunks encoding['chunks']=(20,) for variable named 'v' would overlap multiple dask chunks ((10, 10, 10, 10, 10, 10, 10, 10, 10, 10),). Writing this array in parallel with dask could lead to corrupted data. Consider either rechunking using `chunk()`, deleting or modifying `encoding['chunks']`, or specify `safe_chunks=False`.
================= 2 failed, 215 passed, 122 warnings in 19.36s =================
