Specify production branch

[WhatACotton]

Problem

Our team uses Cloudflare Pages, and we need to get an alias URL for our develop branch. However, our project has set the default branch to develop, instead of the main production branch, to prevent accidental PRs to the production branch.

The current implementation seems to recognize the production branch based on whether it is the default branch or not. As a result, we are unable to get an alias URL for our develop branch.

Solution

To address this issue, I have implemented a feature that allows users to explicitly specify the production branch. This gives us more control and flexibility in managing our deployment workflow, even when the default branch is not the production branch.

To generate the sanitized branch name for the alias URL, I used the code from this GitHub repository. This code is based on this discussion in the Cloudflare community forums.

The branch name sanitization process ensures that the generated alias URL conforms to the required format and does not include any invalid characters or patterns.

As this is my first Pull Request, I would appreciate any guidance or suggestions to improve the quality of my contribution.
