`_Py_atomic_store_char_relaxed` uses wrong memory ordering

[colesbury]

Bug report

cpython/Include/cpython/pyatomic_gcc.h

Lines 520 to 522 in ebc24d5

	static inline void
	_Py_atomic_store_char_relaxed(char *obj, char value)
	{ __atomic_store_n(obj, value, __ATOMIC_RELEASE); }

__ATOMIC_RELEASE should be __ATOMIC_RELAXED.

It's not really a correctness issue because __ATOMIC_RELEASE is strong than __ATOMIC_RELAXED, but we should fix the typo.
