RUSTSEC-2024-0332: Degradation of service in h2 servers with CONTINUATION Flood

[github-actions]

Details
Package	h2
Version	0.3.24
URL	n/a
Patched Versions	^0.3.26 OR >=0.4.4
Aliases	GHSA-q6cp-qfwq-4gcv

An attacker can send a flood of CONTINUATION frames, causing h2 to process them indefinitely.
This results in an increase in CPU usage.

Tokio task budget helps prevent this from a complete denial-of-service, as the server can still
respond to legitimate requests, albeit with increased latency.

Patches available for 0.4.x and 0.3.x versions.
