Skip VSAM Init

[sakshibobade21]

Proposed changes

This PR addresses Issue:

1. Implements a check to determine if the Zowe PAX version is greater than or equal to 3.
2. If version is >= 3, displays a dropdown for users to select the storage mode, pre-filled with the value from the YAML file if available.
3. If the user selects VSAM, the VSAM initialization form is displayed.
4. If Infinispan is chosen, the VSAM initialization form is hidden.
5. If the version is >= 3 and the VSAM initialization is skipped, the review stage will not block the user from proceeding to the final stage.
