`astro:env` secrets may throw on static pages

astro:env

📋 Page(s) affected (or suggested, for new content)

https://docs.astro.build/en/guides/environment-variables/

📋 Description of content that is out-of-date or incorrect

See #14504 for context. If you are in such situation:

• You have public and secret server vars
• You do not use secrets on prerendered pages
• You use public server vars on prerendered pages
• You do not provide secrets during the build since they're not technically required
• You do not have env.validateSecrets: true

Then an error will be thrown saying that your secrets are missing. That's because as soon as the astro:env/server module is imported, even secrets are evaluated. There's nothing we can do about it unfortunately.

Solution is to pass fake values during the build to avoid errors.
