Andrew Hopp 9944982ec0 Add note about application startup delay in Docker Compose tutorial (#23621 )

## Summary

Adds a note to the Docker Compose tutorial clarifying that the
application may take 10-15 seconds to fully start after running `docker
compose up -d --build`.

## Changes

Updated step 5 in the "Start the application" section to inform users
that the application may not be immediately accessible at
`localhost:3000` and that they should wait a moment and refresh if the
page doesn't load right away.

## Why this change is needed

When users run `docker compose up`, Docker reports containers as
"Started" once they're running, but the applications inside (Node.js app
and MySQL database) still need time to initialize and connect. This
causes confusion for beginners who expect immediate accessibility after
seeing "Container started" in the CLI output or within the GUI.

## Related Issue

Fixes #23500
