docs: update articles for production build change

[tltv]

Removed production profile from articles that use example apps that build or will build production package without any production profile.

Part of vaadin/flow#22464

WIP: starters are not updated yet and they are pending on new Spring Boot 4 release that enables removal of the production profile.

AI Language Review

• In the Build a Project section, the instructions for making a production build have changed the activation from the production profile to the package goal. Ensure that end users understand that in the new process, they don't need to activate a profile to build for production.
• For the Building with Commercial Components section, verify that the change from package -Pproduction to clean package applies correctly to this context. Since commercial components might require specific handling, ensure that the provided instructions are adequate for both scenarios.
• In the Deploying Using Docker section, the steps for creating a production build of a Vaadin application have also replaced clean package -Pproduction with clean package. Confirm if this modification aligns with the deployment requirements on Docker.
• In the Production Build section, ensure that the explanation about how to set up the vaadin-maven-plugin for manually created pom.xml files correctly reflects the necessary setup to substitute the previous production profile approach.
• Check whether the language transition presents potential misunderstandings about the criteria for production builds, especially in the Enabling Production Builds and Excluding Development Server Module instructions. Readers who previously relied on using the production profile may need clarification.
• For the Known Issues section in the Quarkus documentation, confirm that reference adjustments such as BOM positioning in the pom.xml are sufficiently clear, especially when dealing with conflicts between Vaadin and Quarkus BOM positioning.

LGTM. Couple of non-blocking comments.

I'd move this snippet to up (before a snippet with profile) so as to make it a primary recommended way for spring apps.

Would be easier to read if this can give a link to the fragment where the production profile is defined.
