Relax http2 version bound to allow 5.3.10

[domenkozar]

Summary

The current version bound for http2 is >= 5.3.9 && < 5.3.10 in grapesy.cabal:

grapesy/grapesy/grapesy.cabal

Lines 177 to 181 in 4ce0c73

	-- We pin very specific versions of http2.
	--
	-- New versions should be tested against the full grapesy test suite
	-- (regular tests and stress tests).
	, http2 == 5.3.9

This prevents building with http2-5.3.10 which is now available and is required by other packages in nixpkgs (specifically http2-tls requires tls >= 2.1.10 which in turn requires newer http2).

Testing

I've tested building grapesy with http2-5.3.10 in nixpkgs by relaxing the version bound (jailbreak). The package builds successfully.

However, the tests fail to compile with a duplicate IsLabel instance error. This appears to be a separate issue from the http2 version bound.

Request

Would it be possible to relax the http2 version bound to allow 5.3.10?

If you'd prefer to test with http2-5.3.10 first before relaxing the bound, I understand. The main goal is to allow downstream package managers to use consistent http2/tls versions across the ecosystem.

Bounds on http2 must be managed very carefully, there have been many subtle breaking changes in the past, so thorough testing is definitely required. I can look into this.
