Breaking: #67098 - Correct required-parameter in TextfieldViewHelper

See forge#67098

Description

The value comparison of the required parameter has been corrected. Prior to this change, a textfield was required as soon as it had a parameter "required" set to any value even if this value was set to FALSE, the textfield was still required.

Impact

Textfields with required="FALSE" are not required any longer.

Affected Installations

Every installation that uses the textfield view helper with the required attribute.

Migration

No migration is necessary.
