Subject: sci-libs/cantera: 2.5.0 version bump

Cantera now use yaml as input format and thus depends on
'dev-cpp/yaml-cpp' and 'dev-python/ruamel-yaml'.

The following dependences in DEPEND are actually not required to build
and if absence the appropriate 2 tests just will be skipped:

test? (
	python? (
	$(python_gen_cond_dep '
		dev-python/h5py[${PYTHON_MULTI_USEDEP}]
		dev-python/pandas[${PYTHON_MULTI_USEDEP}]
        ')
)

Closes: https://github.com/gentoo/gentoo/pull/19448
