nx does not honor package.json based workspace settings for projects

[techfg]

Current Behavior

Using the workspace based approach to identify nx projects, nx does not seem to be properly identifying projects based on items in the workspaces property of package.json.

Given a file system of the below, the following issues arise:

Scenario 1 - Basic project

  "workspaces": [
    "packages/*",
    "packages/ui/*"
  ]

Actual Behavior - Works as expected, all 4 projects are properly identified

Scenario 2 - Adjusted workspaces to only include root level folders inside of packages directory

  "workspaces": [
    "packages/*"
  ]

Actual Behavior: @nx-workspaces-not-honored/uilib1 and @nx-workspaces-not-honored/uilib2 are listed in projects with their fully qualified names

Scenario 3 - Added @nx/eslint to packagelib2

  "workspaces": [
    "packages/*"
  ]

Actual Behavior: @nx-workspaces-not-honored/packagelib1fake is listed as a project in addition to @nx-workspaces-not-honored/uilib1 and @nx-workspaces-not-honored/uilib2 all with their fully qualified names.

Scenario 4 - Explicitly exclude workspace folders

  "workspaces": [
    "packages/*",
    "!packages/packagelib1/src/packagelib1fake",
    "!packages/ui/**"
  ]

Actual Behavior: @nx-workspaces-not-honored/packagelib1fake is listed as a project in addition to @nx-workspaces-not-honored/uilib1 and @nx-workspaces-not-honored/uilib2 all with their fully qualified names.

Expected Behavior

• Scenario 1 - Works as expected
• Scenario 2 - Only packagelib1 and packagelib2 should be listed as projects
• Scenario 3 - Only packagelib1 and packagelib2 should be listed as projects
• Scenario 4 - Only packagelib1 and packagelib2 should be listed as projects

Additional Information

1. This seems similar/same as Nx does not ignore package.json based on workspace settings #22348
2. This seems to be two different issues since it requires eslint to trigger Scenario 3. If it's preferred that I create a separate issue for that one, just let me know, happy to do so.
