Replace [!INFO] callouts with Hugo notes shortcode

[Copilot]

This PR replaces all GitHub-style [!INFO] callout syntax with the proper Hugo {{% notes type="info" %}} shortcode format.

Background

The repository contained 20 instances of the [!INFO] callout format, which is GitHub-specific markdown syntax that doesn't render properly in Hugo (the static site generator used for the Pulumi documentation). These callouts need to be converted to the Hugo notes shortcode format as specified in the repository's STYLE-GUIDE.md.

Changes

Pattern replaced:

> [!INFO]
> Content text here

With:

{{% notes type="info" %}}

Content text here

{{% /notes %}}

Files Modified

• 17 markdown files updated (2 in content/what-is/, 15 in content/blog/)
• 20 total replacements made

Validation

• ✅ All files pass markdown linting (0 errors)
• ✅ All files pass Prettier formatting checks
• ✅ Confirmed 0 remaining [!INFO] callouts in repository
• ✅ Created exactly 20 new {{% notes type="info" %}} shortcodes

The changes ensure consistent rendering of informational callouts across the documentation site and align with the repository's style guide.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• cdn.cypress.io
  • Triggering command: /usr/local/bin/node index.js --exec install (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Find all usages of the [!INFO] shortcode and replace them with the {{< notes type="info" >}} shortcode
