Start: Domains, do not submit when removing the free domain

[escapemanuele]

Context: p1729251522419809-slack-C073776NJ66

Proposed Changes

Avoid submitting the Domains step when removing the free domain.

Why are these changes being made?

Removing the free domain shouldn't trigger the step submission

Testing Instructions

• Go to /start and in the domains step add and remove the free domain
• Check that calypso_signup_actions_submit_step (step: domains) is not triggered.
• Check that it triggered when actually submitting the step

Here is how your PR affects size of JS and CSS bundles shipped to the user's browser:

Async-loaded Components (~15 bytes removed 📉 [gzipped])

name                             parsed_size           gzip_size
async-load-signup-steps-domains       -103 B  (-0.0%)      -15 B  (-0.0%)

React components that are loaded lazily, when a certain part of UI is displayed for the first time.

What is parsed and gzip size?

Parsed Size: Uncompressed size of the JS and CSS files. This much code needs to be parsed and stored in memory.
Gzip Size: Compressed size of the JS and CSS files. This much data needs to be downloaded over network.

@escapemanuele, I just ran a quick test with the classic flow and can confirm that calypso_signup_actions_submit_step (step: domains) is no longer triggered when a selected free domain is removed 🎉
