chore(deps): Bump xxhash from 3.7.1 to 3.8.0

[dependabot]

Bumps xxhash from 3.7.1 to 3.8.0.

Release notes

Sourced from xxhash's releases.

v3.8.0

• Speed up module-level one-shot digest(), intdigest(), and hexdigest() functions by switching them to METH_FASTCALL.
• Keep one-shot argument handling consistent with hash constructors, including positional and keyword input/seed arguments, duplicate argument errors, and oversized seed wrapping.
• Fix error handling in the xxh3_128 integer digest path so allocation failures are reported cleanly.
• Fix Python 3.8 builds by adding a PyModule_AddType compatibility fallback with correct reference counting.
• Correct type stubs for xxh64_digest(), xxh64_hexdigest(), and xxh64_intdigest(), they were incorrectly aliased to xxh3_64 functions.

v3.7.2

• Register the "benchmark" pytest mark to avoid PytestUnknownMarkWarning
• Update C extension docstrings and remove stale comments
