change: [M3-8379] - Disable Region in OS tab for unsupported distributed images

[hana-akamai]

Description 📝

Not all Linux Distributions in the Linode Create OS tab support distributed regions. We want to disable a region if the selected OS does not have a distributed capability similar to the Images tab

Changes 🔄

• Remove specific check for linodeCreateTab in getDisabledRegions so that any selected image that does not have the distributed-sites capability is disabled
• Minor UI positioning fix for distributed helper text w/ region error text

How to test 🧪

Prerequisites

(How to setup test environment)

• Ensure your account has the new-dc-testing, new-dc-testing-gecko, edge_testing and edge_compute customer tags
• Pull this PR and run it locally pointing to dev API

Reproduction steps

(How to reproduce the issue, if applicable)

• Checkout develop locally while pointing to the dev API
• Go to the Linode Create flow
• Notice that distributed regions are not disabled for unsupported distributed images (no distributed icon, e.g. Debian 11)

Verification steps

(How to verify changes)

• Go to the Linode Create flow and verify the v1 and v2 flows for Gecko Beta & Gecko LA/GA
  • To test Gecko Beta locally, you can add the following to useFlags.ts:
  • We do not want to change the LD flag globally since other teams rely on it
  • ...mockFlags,
    gecko2: {
    enabled: true,
    ga: false
    }
• Verify unsupported distributed regions (no distributed icon, e.g. Debian 11)
  • Gecko LA/GA: Regions in the Distributed tab should be disabled with tooltip
  • Gecko Beta: Distributed regions in the single dropdown should be disabled with tooltip
• Verify supported distributed regions (distributed icon, e.g. Ubuntu 24.04 LTS)
  • Gecko LA/GA: Regions in the Distributed tab should not be disabled
  • Gecko Beta: Distributed regions in the single dropdown should not be disabled
