BREAKING CHANGE
<!-- Please make sure you have read the submission guidelines before
posting an PR -->
<!--
https://github.com/nrwl/nx/blob/master/CONTRIBUTING.md#-submitting-a-pr
-->
<!-- Please make sure that your commit message follows our format -->

## Current Behavior
<!-- This is the behavior we have today -->
* `@nx/devkit` supports Nx 17 - 20.
* Node 18 - 22 is supported
* `ExecutorContext.projectGraph`, `ExecutorContext.nxJsonConfiguration`,
and `ExecutorContext.projectsConfigurations` is marked as optional
because `ExecutorContext` in some versions of Nx did not have them.
* `ExecutorContext.workspace` is marked as optional because
`ExecutorContext` in some versions of Nx did not have the above
properties which contain the same information.
* `ProjectGraphNode` is deprecated.
* `NxPluginV1.processProjectGraph` was deprecated long ago and there has
been a warning since.
* `appRootPath` has been deprecated for a long time.
* `parseTargetString` had a variant that did not take either the project
graph or the executor context.
* `readNxJson` has a variant which does not take a tree. This was not
clearly deprecated.
* There are handlers to require from `@nx/` instead of `@nrwl`
* Nx tries to get a root install from `@nrwl/cli`
## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->
* `@nx/devkit` supports Nx 19 - 21.
* Node 20 - 22 is supported
* `ExecutorContext.projectGraph`, `ExecutorContext.nxJsonConfiguration`,
and `ExecutorContext.projectsConfigurations` is marked as required
because `ExecutorContext` in Nx 19+ is guaranteed to have them.
* `ExecutorContext.workspace` is removed because the same information is
available in the above properties
* `ProjectGraphNode` is removed.
* `NxPluginV1` is no more. All plugins should be `NxPluginV2`.
* `workspaceRoot` is the replacement for `appRootPath`. `appRootPath` is
removed.
* `parseTargetString` no longer has a variant that did not take either
the project graph or the executor context.
* `readNxJson` still has a variant which does not take a tree but it's
clearly deprecated to be removed in Nx 21.
* `@nrwl` packages are no more so we don't have to redirect requires
anymore.
* `@nrwl/cli` is no more so Nx shouldn't try to get a root install there
*
