Dynamic links for different environments

[asvae]

We have many different environments, but all links are hardcoded to production (master) environment. So if you follow from develop landing to demo - you'll land on production demo. Which might be confusing.

What we want instead is to have these links defined as part of the env in railway config - so that landing and demo links environments match.

Here are all the links:

• master - landing: admin.vuestic.dev, demo: admin-demo.vuestic.dev
• develop - landing: admin-develop.vuestic.dev, demo: admin-demo-develop.vuestic.dev
• experimental - landing: admin-experimental.vuestic.dev, demo: admin-demo-experimental.vuestic.dev
