Description of problem:

The tooltip text associated with the "Existing VPC" section under the "Virtual Private Cloud (VPC) subnet settings" step in the installation wizard appears to be incorrect.

• The current tooltip reads:

  "Install into a non-default subnet shared by another account in your CP organization."
  This description refers to Shared VPCs, which is misleading in this context.

• Additionally, the link text says:

  "Learn more about GCP shared VPC",
  which further reinforces the incorrect assumption that Shared VPC is required or implied here.

However, selecting "Existing VPC" should refer to using a custom VPC within the same project, not a Shared VPC. The tooltip and link should be updated to reflect this accurately.

Steps to Reproduce:

1. Launch the OCM UI.
2. Open the OSD cluster creation wizard.
3. In the Billing Model step:
4. Select Subscription type: Annual: Fixed capacity subscription from Red Hat.
5. Select Infrastructure type: Customer Cloud Subscription.
6. Click Next and choose GCP as the cloud provider.
7. Continue through the wizard until you reach the Networking Configurations step.
8. Select the checkbox: "Install into existing VPC."
9. Click Next to proceed to the Virtual Private Cloud (VPC) subnet settings step.
10. Click the question mark icon associated with the "Existing VPC" section.
11. Review the tooltip content that appears.

Actual results:

At step 11,

• The current tooltip reads:

  "Install into a non-default subnet shared by another account in your CP organization."

• Additionally, the link text says:

  "Learn more about GCP shared VPC",

Expected results:

• The tooltip should be,

  "Install into a user-defined subnet within a custom VPC network that is provisioned and fully managed within the same GCP project"

• Additionally, the link text should be,

  "Learn more about installing into an existing VPC",
