Bump h2

[CriesofCarrots]

Problem

Cargo audit failure

Summary of Changes

Bump h2 to v0.3.26

[CriesofCarrots]

Sorry, rebased with changes to programs/sbf/Cargo.lock. I forgot that we have to run cargo update on programs/sbf/Cargo.toml directly instead of ./scripts/cargo-for-all-lock-files.sh tree

Backports to the stable branch are to be avoided unless absolutely necessary for fixing bugs, security issues, and perf regressions. Changes intended for backport should be structured such that a minimum effective diff can be committed separately from any refactoring, plumbing, cleanup, etc that are not strictly necessary to achieve the goal. Any of the latter should go only into master and ride the normal stabilization schedule.
