feat: esm with type module

[cseas]

Description

Changes the project to use ESM files with type module.

The ignoreBuildErrors config is needed to ignore type errors caused by Next.js bugs:

• Tree shaking doesn't work with Typescript barrel files vercel/next.js#12557 (comment)
• NextJS does not support moduleResolution: Node16 vercel/next.js#44095
• "next build" doesn't recognise node subpath export patterns in npm packages vercel/next.js#46267

📦 Next.js Bundle Analysis

This analysis was generated by the next.js bundle analysis action 🤖

⚠️ Global Bundle Size Increased

Page	Size (compressed)
global	95.61 KB (🟡 +9.84 KB)

Details

The global bundle is the javascript bundle that loads alongside every page. It is in its own category because its impact is much higher - an increase to its size means that every page on your website loads slower, and a decrease means every page loads faster.

Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis

Four Pages Changed Size

The following pages changed size from the code in this PR compared to its base branch:

Page	Size (compressed)	First Load
/learn	275.52 KB (🟢 -7.63 KB)	371.13 KB
/learn/[id]	275.52 KB (🟢 -7.63 KB)	371.13 KB
/posts	275.52 KB (🟢 -7.63 KB)	371.13 KB
/posts/[id]	275.52 KB (🟢 -7.63 KB)	371.13 KB

Details

Only the gzipped size is provided here based on an expert tip.

First Load is the size of the global bundle plus the bundle for the individual page. If a user were to show up to your website and land on a given page, the first load size represents the amount of javascript that user would need to download. If next/link is used, subsequent page loads would only need to download that page's bundle (the number in the "Size" column), since the global bundle has already been downloaded.

Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis

Next to the size is how much the size has increased or decreased compared with the base branch of this PR. If this percentage has increased by 20% or more, there will be a red status indicator applied, indicating that special attention should be given to this.
