Bug: [BUG (CYPRESS)] Hard coded card expiry resulting in few tests to fail



updating card expiry resulted in unintended after effects for specific connectors like adyen where it expects the user to pass a specific card expiry year (`30` instead of `55` or any other number).

we cannot hard code connector names in spec files to exclude them from getting updated. neither we can go ahead and pull in another set of connector configs for this. so, i feel, it is better to just restrict that field from getting updated.

## Description
<!-- Describe your changes in detail -->

the reason behind this pr is that there are a few connectors like adyen that expects the user to pass specific card expiry year and having it hard coded like we had until now results in unintended issues resulting the tests to fail.

can focus on the implementation (unless it is an obvious bug or documentation fix
that will have little conversation).

updating card expiry resulted in unintended after effects for specific connectors like adyen where it expects the user to pass a specific card expiry year.
we cannot hard code connector names in spec files. neither we can go ahead and pull in another set of connector configs for this.

so, it is more viable to remove the entire field from getting update since updating one field should be more than enough.

## How did you test it?
<!--
Did you write an integration/unit/API test to verify the code changes?
Or did you test this change manually (provide relevant screenshots)?
-->

ran test against adyen since it was the one threw this error. not sure about other connectors but yeah, this change should fix them as well:
