Pull request overview

This PR fixes broken GitHub Markdown callout syntax in the documentation by moving TIP callouts from inside code blocks to outside them. GitHub Markdown callouts (using > [!TIP] syntax) need to be placed outside code fences to render properly. The fix is applied consistently across the main English README and its Portuguese and French translations.

Changes:

• Repositioned GitHub Markdown TIP callouts from inside Docker command code blocks to after the closing code fence in all three README files

There are two extra blank lines here that are not present in the corresponding sections of README.md and README.pt-br.md. For consistency across all three documentation files, these extra blank lines should be removed. The other README files have only one blank line after the TIP callout before the next section.

LGTM, but do we need to also update the README for other languages?

Correct fix. GitHub Markdown callouts (> [!TIP]) must be placed outside of fenced code blocks (triple backticks) to render properly. Moving the callout after the closing ``` in all three READMEs fixes the rendering.

One minor nit: the French README adds an extra blank line at the end of the callout block (two blank lines after the callout), while the English and Portuguese versions do not. Cosmetic only.

LGTM.
