ngtcp2: Fix build error due to symbol name change #6271
ngtcp2/ngtcp2@76232e9 changed the name.
http3 builds in CI broke today due to symbol rename in ngtcp2 so I propose we change the name here too. Unfortunately with this change users that build with old ngtcp2 will then get build errors...
Yes. This goes for all our HTTP/3 builds until at least parts of those builds are done with release versions of the involved libraries. Until then, we just keep up with the development versions.
