This PR removes installation instructions for Nx < 18 since it has
fallen out of support window. Users can always `npm install <plugin>` as
usual if they are on an unsupported Nx version, but the docs will assume
`nx add` moving forward.
The changes are on the plugin overview page:
https://nx-dev-git-docs-remove-nx-pre-18-install-nrwl.vercel.app/nx-api
## Current Behavior
Missing documentation on how to use Playwright's `--project` argument
with Nx.
Because Nx also has a `--project` argument, passing it to the command
like `nx e2e app --project=firefox` will result in the `--project` being
stripped from the command that is sent to Playwright.
## Expected Behavior
The fix is simple enough, change the command to be `nx e2e app --
--project=firefox` to ensure the argument is forwarded correctly to
Playwright.
Add some information to the Playwright plugin's overview documentation
to explain this.

This PR updates examples in `.md` files (both docs and blog posts) to
use positional args. Nx 20 changes the position arg to be either
`directory` for apps/libs or `path` for artifacts (e.g. components).
So before you'd do this:
```
nx g app myapp --directory=apps/myapp
nx g lib mylib --directory=libs/mylib
nx g lib mylib --directory=libs/nested/mylib
nx g lib @acme/foo --directory=libs/@acme/foo --importPath=@acme/foo
nx g component foo --directory=libs/ui/src/foo --pascalCaseFiles
```
Will now be simplified to
```
nx g app apps/myapp
nx g lib libs/mylib
nx g lib libs/nested/mylib
nx g lib libs/@acme/foo # name and import path are both "@acme/foo"
nx g component libs/ui/src/foo/Foo
```
For cases where `name` and `importPath` need to be changed, you can
always manually specify them.
```
nx g lib libs/nested/foo # name is foo
nx g lib libs/nested/foo --name=nested-foo # specify name with prefix
nx g lib libs/@acme/foo --name # use "foo" as name and don't match importPath
nx g lib libs/@internal/foo --importPath=@acme/foo # different importPath from name
<!-- 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. -->
