docs: use pGPU alias

[katexochen]

Previously, Contrast allowed GPU model-specific resource types (such as nvidia.com/GH100_H100L_94GB) instead of the generic nvidia.com/pgpu to support heterogeneous hardware configurations. However, as Kata upstream isn't supporting this, this is switched to setup the Nvidia operator with the pGPU alias instead. We might be able to revert to the resource specific annotations in the future, depending on the upstream support for it.

As a user, follow the updated setup instructions for the Nvidia GPU operator and use nvidia.com/pgpu in resource limit.

Do the documentation changes need to be backported?

Changes to /docs/docs won't be visible until the next release.
If you are fixing something in the docs that should be immediately visible, the changes needs to be made to both /docs/docs and /docs/versioned_docs/version-X.Y, where X.Y is the version of the latest minor release.
This can be done in this same PR.

• Yes, this should be backported to the current version of the docs.
• No, the PR only contains docs changes relevant for future versions.
