feat(react): undeprecate svgr option for Next.js apps since --turbo supports it (#30909)
This PR delays deprecation of `svgr` for `@nx/next`, as Turbopack
supports it now.

This PR also deprecates all SVGR support for v22. It is not a well-used
feature, and the webpack plugin is not maintained. We'll ensure in v22
to add the SVGR webpack plugin to userland configs, but we'll not
maintain it ourselves moving forward.

<!-- If this is a particularly complex change or feature addition, you
can request a dedicated Nx release for this pull request branch. Mention
someone from the Nx team or the `@nrwl/nx-pipelines-reviewers` and they
will confirm if the PR warrants its own release for testing purposes,
and generate it for you if appropriate. -->

## Current Behavior
<!-- This is the behavior we have today -->

## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->

## Related Issue(s)
<!-- Please link the issue being fixed so it gets closed when this is
merged. -->
