build(deps-dev): update fakeredis requirement from >=2.20 to >=2.37.1 in /backend

[dependabot]

Updates the requirements on fakeredis to permit the latest version.

Release notes

Sourced from fakeredis's releases.

v2.37.1

What's Changed

🐛 Bug Fixes

• fix: honor the FILTER-EF (max filtering effort) option in VSIM — the value was previously parsed but ignored, so a low FILTER-EF could return filter matches that real Redis skips
• fix: ZPOPMIN/ZPOPMAX in RESP3 now return a flat [member, score] pair when no count is given (an array of pairs is only returned when an explicit count is passed), matching real Redis
• fix: ZPOPMIN/ZPOPMAX now reject a negative count with value is out of range, must be positive
• fix: ZPOPMIN/ZPOPMAX/BZPOPMIN/BZPOPMAX/ZMPOP/BZMPOP now delete the sorted set key once its last member is popped
• fix: LTRIM now signals the key as modified even when the trim is a no-op, so a WATCH on that key correctly aborts the following transaction, matching real Redis
• fix: align stream group errors with Redis — XPENDING on a missing key or unknown group now raises NOGROUP instead of returning 0/an empty array, and neither XPENDING nor XINFO GROUPS creates the key as a side effect (#532)

🧰 Maintenance

• perf: VADD/VSIM keep a row-oriented matrix of the vector set resident and reuse it, instead of restacking every stored vector on each call; re-adding an existing member now replaces its row rather than leaving a stale one
• perf: cache compiled JSONPath objects in the JSON stack mixin (#538)
• build: drop Python 3.9, target Python 3.10+ (#534)
• Update to redis-py 8.1
• refactor: modernize typing for Ruff 0.16 defaults (#533)
• test: refactor hypothesis tests
