docs: add workaround for PHP plugin tool install order with corporate certs (#437)

* docs: add workaround for PHP plugin tool install order with corporate certs

As of @lando/php 1.10.0+, tools like Composer are installed before
user-defined build_as_root commands, breaking corporate proxy cert
workflows. Documents the workaround of disabling automatic tool
installation and manually installing after the cert is in place.

Closes lando/php#236

* fix: add broken external links to netlify checklinks todoPatterns

Docker dockerfile-release-notes has a fragment redirect issue and
jeffgeerling.com returns 301 instead of expected 302. Both are
external sites we can't control.

* Update composer installation command in tips guide

Removed version number from composer installation script.

+::: warning PHP plugin tools install before user build steps
+As of `@lando/php` 1.10.0+, tools like Composer are installed during the build phase **before** your `build_as_root` commands run. This means the cert won't be in place yet when tools try to download, causing SSL errors.
+
+To work around this, disable automatic tool installation and install them manually after your cert is in place:
+
+```yaml
+services:
+  appserver:
+    composer_version: false # Prevent automatic composer install
+    build_as_root:
+      - cp /app/yourcert.crt /usr/local/share/ca-certificates/
+      - chmod 644 /usr/local/share/ca-certificates/yourcert.crt
+      - update-ca-certificates
+      - /etc/lando/service/helpers/install-composer.sh # Install composer after cert
+```
+
+The same approach applies to other PHP tools — disable their automatic installation via config, install your cert first, then install the tools manually using the helper scripts in `/etc/lando/service/helpers/`.

 #### Adding Certs for PHP cURL Requests
 If you make external requests with the PHP process in your app, you will also need to include the cert in your appserver's `php.ini` file:
