Align Validation Message for Branch Name Field in EDP

[callmevladik]

There is a discrepancy in the validation message provided when a user attempts to create a new branch with an invalid name in a codebase, specifically for EDP and the default versioning type. The goal is to standardize the validation message to enhance user understanding and guide correct input.

Steps to Reproduce:

1. Attempt to create a new branch in a codebase with an invalid name (e.g., 'TEST').

Actual Result:

The error message displayed is 'Enter valid release branch name'.

Expected Result:

The error message should guide the user with specific criteria, similar to when the field is left empty: 'Branch name may contain only: lower-case letters, numbers, slashes, dashes, and dots. Can start and end only with lower-case letters and numbers. Minimum 2 characters.'
