fix: update links in README for VertiGIS Studio Developer Center documentation (#65)

fix: update documentation URLs to use correct domain

Several documentation links were pointing to the an incorrect domain (developers.vertigis.com).
Updated these to use the current domain (developers.vertigisstudio.com) to ensure users
can access the correct documentation resources.

Changes:

    Updated deployment guide link
    Updated Developer Center links
    Updated SDK documentation link
