conformance: Rename infra namespace

[davidjumani]

What type of PR is this?

Add one of the following kinds:
/kind cleanup

Optionally add one or more of the following kinds if applicable:
/area conformance-test

What this PR does / why we need it:
This renames the inference conformance infra from gateway-conformance-infra to inference-conformance-infra.
This allows clean back-to-back runs of the Gateway API and Inference Extension conformance tests avoiding any failures caused by using the same namespace

Which issue(s) this PR fixes:

Fixes #1315

Does this PR introduce a user-facing change?:

Rename the conformance infra namespace to `inference-conformance-infra`

@davidjumani did you run the conformance test suite after making these changes? If not, you can follow these steps and instead of calling make gie-conformance, run the conformance suite from your gateway-api-inference-extension fork:

$ go test -v ./conformance -args -debug=true -gateway-class=kgateway
