Add supported browsers for Strapi Admin in Quick Start Guide prerequisites

[singhvishalkr]

Summary

Documents the default Browserslist targets used when building the Strapi Admin panel, in the Quick Start Prerequisites section (via the shared installation prerequisites snippet).

Closes #2905

Background

Strapi resolves the Admin build target with browserslist.loadConfig({ path: cwd }) and falls back to the default queries defined in packages/core/strapi/src/node/create-build-context.ts:

• last 3 major versions
• Firefox ESR
• last 2 Opera versions
• not dead

Changes

• Added a Web browser (Admin panel) bullet to docusaurus/docs/snippets/installation-prerequisites.md noting the default Browserslist query and linking to browsersl.ist for the current coverage matrix.
• Mentioned that projects can override the defaults with a Browserslist configuration at the project root.

How to verify

1. cd docusaurus && yarn && yarn dev -- open the Quick Start page and confirm the Prerequisites block includes the browser note.
2. yarn build -- ensure the site builds with no broken links.

Thank you, @singhvishalkr, for your very first contributions to this repository and for the many PRs 😊

I'm going to fix this manually this time, but for the next PRs that you might create, please ensure PR titles meet the requirements defined in git-rules.md. Please ensure your AI tool includes these rules in its context (git-rules.md is mentioned in AGENTS.md)

In short:

• PR names should not be prefixed with [docs], [cms], [feat], [fix], etc. We use GitHub labels for categories.
  Wrong example: docs(cms): note supported browsers… → Correct example: Add note about supported browsers…
• PR names should start with action verbs (for fixes, additions, removals, etc;), or only include feature names (for new content)

Apart from that, please also refrain from using bold to highlight content. I know this is something most AI tools do, but this is not consistent with our content.

The PR is now approved, merged, should be live on docs.strapi.io in a few minutes, and will be mentioned in the next weekly snapshot release.

Thank you for your understanding
