Supabase fails to load in web component

# Bug report - [x] I confirm this is a bug with Supabase, not with my own application. - [x] I confirm I have searched the [Docs](https://docs.supabase.com), GitHub [Discussions](https://github.com/supabase/supabase/discussions), and [Discord](https://discord.supabase.com). ## Describe the bug Adding a component that uses Supabase to [Shoelace components](https://github.com/shoelace-style/shoelace) produces the following error: ``` SyntaxError: The requested module './../../../node-fetch/lib/index.js' does not provide an export named 'default' (at PostgrestBuilder.js:1:8) ``` Which references [this line in PostgrestBuild.js](https://github.com/supabase/postgrest-js/blob/master/src/PostgrestBuilder.ts#L2): ``` // @ts-ignore import nodeFetch from '@supabase/node-fetch'; ``` ## To Reproduce Steps to reproduce the behavior, please provide code snippets or a repository: 1. `git clone https://github.com/shoelace-style/shoelace` 2. `cd shoelace` 3. `npm install @supabase/supabase-js` 4. `npm install` 5. `npm run build` 6. `npm run test` => All tests pass, check. 7.
