Password not Saved for Secret Created Through Pipeline Form

Description of problem:

When starting a new pipeline through the "new pipeline" form and adding a secret (image registry or git / basic auth) at the bottom, the set password is not persisted in the secret. 

Workaround : After the pipeline fails for the first time, the secret itself can be fixed by setting the password directly on the secret again.

Prerequisites (if any, like setup, operators/versions):

Tested on OCP 4.14 and Pipelines 1.14.3

Steps to Reproduce

• Create any pipeline (e.g through new app form)
• Click on "Start Pipeline"
• Scroll down to "Show credential options" and then "add Secret"
• Enter a image Registry / Basic Auth Secret
• Enter username and password
• Run the pipeline

Actual results:

• The pipeline  will fail if it is using the secret
• The created secret has no password set (only the username)

Expected results:

• The pipeline succeeds using the secret
• The password is set in the secret

Reproducibility (Always/Intermittent/Only Once):

Always
