docs: fix broken jetify.com documentation links (404s)

[mikeland73]

Summary

Fixes #2769

The documentation links in README.md (and many example READMEs) point to the old URL prefix https://www.jetify.com/devbox/docs/..., which now returns 404. The docs site moved to the https://www.jetify.com/docs/devbox/... scheme.

This PR normalizes every broken occurrence of jetify.com/devbox/docs → jetify.com/docs/devbox.

Why this is the correct target

The repo already uses both schemes inconsistently. Notably, the .envrc files that devbox itself generates (e.g. examples/development/go/hello-world/.envrc) already use the new, working scheme:

# check out https://www.jetify.com/docs/devbox/ide_configuration/direnv/

and several example READMEs already use https://www.jetify.com/docs/devbox/installing-devbox/index. This change brings the remaining stale links in line with that canonical scheme.

Note: The container running this fix has no outbound access to jetify.com (all requests return 403), so the target scheme was confirmed from in-repo evidence rather than a live HTTP check. The two links explicitly cited in the issue are both covered:

• https://www.jetify.com/devbox/docs/cli_reference/devbox/ → https://www.jetify.com/docs/devbox/cli_reference/devbox/
• https://www.jetify.com/devbox/docs/contributor-quickstart/ → https://www.jetify.com/docs/devbox/contributor-quickstart/

Changes

• 28 link fixes across 16 files (README.md, examples/**/README.md, plugins/README.md, vscode-extension/src/devbox.ts).
• Image/shield URLs (jetify.com/img/devbox/..., jetify.com/devbox/img/...) were intentionally left untouched — only the /devbox/docs/ documentation prefix was changed.

Testing

• No code behavior changes; documentation/links only (plus one VS Code extension "open external URL" string).
• Verified zero remaining occurrences of the broken prefix: grep -rIn "jetify.com/devbox/docs" . returns nothing.
