chore: bump maxminddb from 0.28.1 to 0.29.0

[dependabot]

Bumps maxminddb from 0.28.1 to 0.29.0.

Release notes

Sourced from maxminddb's releases.

0.29.0

• Breaking: Metadata::build_time() now returns Result<SystemTime, MaxMindDbError> instead of panicking on unrepresentable timestamps, and databases whose build_epoch cannot be represented as SystemTime are rejected as invalid during open and verify.
• Breaking: Reader::metadata is now private. Use Reader::metadata() to access validated metadata by shared reference.
• Breaking: Opening a database now rejects unsupported major format versions, unsupported IP versions, and zero-node search trees. Minor format versions are still accepted for forward compatibility.
• Fixed: within() and networks() now handle IPv6 databases without an IPv4 subtree without reading terminal data nodes as tree nodes or panicking while formatting low IPv6 networks.
• Fixed: Skipping ignored or unknown fields now enforces data-section bounds and the maximum nesting depth instead of accepting truncated values or overflowing the stack on deeply nested corrupt data.
• Internal: Added focused benchmarks for network iteration and serde unknown-field skipping, plus metadata build-time conversion, to guard performance-sensitive fixes.
• Documentation: Fixed intra-doc links so docs build with warnings denied, and added a CI check to keep them passing.
