chore: update dependencies ahead of the v0.19 release

[galargh]

Do we also want to include test dependencies in the update process (go get -t in root and go get -u -t in test/dependencies)? Is there anything else we should be taking care of here?

Log:

go get -u
go mod tidy
pushd docs/examples/kubo-as-a-library
go mod tidy
popd
// replace v1.7.0 with v1.12.0 next to opentelemetry deps in go.mod
go mod tidy
pushd docs/examples/kubo-as-a-library
go mod tidy
popd

@galargh we want to update to the next libp2p version to add some fixes and improvements made on ResourceManager

@ajnavarro : agreed on needing to update go-libp2p, but that can be done later? I think this PR is just making sure that we periodically do a general dependency update. We can still do additional ones after the fact.

[ajnavarro]

@BigLep No problem to do it later.
