refactor: use TRAVIS_BUILD_WEB_URL and require Angular 18+

- Use TRAVIS_BUILD_WEB_URL instead of constructing URL manually

- Update README to require Angular 18+ (not 17)
- Fix misleading browserTarget comment in builder.ts
- Remove dead Travis CI link from standalone docs

 This command has the following prerequisites:
 
 - Git 1.9 or higher (execute `git --version` to check your version)
-- Angular project created via [Angular CLI](https://github.com/angular/angular-cli) v17 or greater
