[BUG] Installation URL not accurate for any file other than mod.ts

[t8]

Describe the bug
If a user were to use an "index" file other than mod.ts, the registry would not update this information.

To Reproduce
Publish a package to the registry that does not use mod.ts as the main script in the project root.

Expected behavior
The index file should be passed through the API to allow the frontend to fetch and set it dynamically.

Screenshots

Desktop (please complete the following information):

• OS: macOS
• nest.land Version: 0.1.0

Additional context
Blob is assigned to this as well because it involves the API.

I'd say we should make a mod.ts file mandatory, as it seems to already be a standard in the Deno community.

[zorbyte]

It's a de facto standard. We shouldn't.

[littledivy]

It's not an official standard though, this should be considered as it might drive away people who have their project working with another index file, they would not want to change it.

Why is this marked as invalid? This issue should definitely be addressed.

[t8]

My apologies. I marked this issue as invalid because the website was showing invalid information. I must have misunderstood the meaning of this tag.

We've implemented an "entry" file for 0.1.3, but this is not added in the frontend yet. This addition will be coming soon!
