Remove cancel button from deploy progress notification

Intent

Resolves #2498
Resolves #2179 (by eliminating the triggering functionality)

Type of Change

• • Bug Fix
• • New Feature
• • Breaking Change
• • Documentation
• • Refactor
• • Tooling

Approach

Code was added within PR: #2071, so I used it as a guide in removing the applicable functionality. I maintained a few minor changes from that PR not directly related to the removed functionality which improved readability.

Deployment in progress now looks like this:

(Note that the screenshot was taken ahead of the incremental progress steps being displayed.)

User Impact

Users will no longer have a "Cancel" option when deploying a project to Connect.

Automated Tests

No impact to existing unit tests was needed, as the code removed did not have coverage.

Directions for Reviewers

Confirm deployment of a project:

• is still functional
• displays the deployment notification without a cancel button
• continues to display the deployment progress within the home view

Checklist

• I have updated CHANGELOG.md to cover notable changes.
