remove entviz library

[migmartri]

We are currently leveraging this library https://github.com/hedwigz/entviz to generate a visualization of the control plane schema

And it will get generated automatically as part of code generation

chainloop/app/controlplane/internal/data/ent/entc.go

Line 33 in 041cd2d

}, entc.Extensions(entviz.Extension{}))

You can open the visualization by running.

make visualize-data-model

The issue is that the library is no longer supported, and we should either remove it or replace it for something like ariga.io/entviz. This new library/CLI has been featured in a more recent blog post. My hesitancy comes because of the fact that it seems to be coupled to a cloud service.

Worse case scenario we can just remove this functionality from the code, it's ok.
