Bumps github.com/twmb/franz-go from 1.21.1 to 1.21.2.

Changelog

Sourced from github.com/twmb/franz-go's changelog.

v1.21.2

This patch release contains two narrow bug fixes and one small feature. Deps are also bumped so that you are force-pinned to a klauspost/compress version that has a stack-splitting bugfix that sometimes affected franz-go.

• PurgeTopicsFromConsuming now correctly persists deleted topics if you also had specific topics paused. Previously, when a topic had partition-level pauses, unpausing the topic itself (while keeping specific partitions paused) was bugged and the topic was stuck in an "all paused" state (thanks @​gorakdev!).

• PollFetches no longer surfaces a spurious UNSTABLE_OFFSET_COMMIT fetch error when an OffsetFetch retry is canceled mid-wait by a rebalance or client close. Observed flaking TestTxnEtl/sticky/848 on KIP-848 consumer groups under transactional load.

• The MSK IAM SASL mechanism now honors AWS_REGION when the broker hostname does not match the standard MSK URL format, allowing connections through custom DNS names (e.g. private link endpoints) (thanks @​janmoritzmeyer0210!).
