fix: add .js to base protocol import in filter sdk

[adklempner]

Problem

Using @waku/sdk fails in browser with this error:

ERROR in ../../../js-waku/packages/sdk/dist/protocols/filter.js 5:0-50
Module not found: Error: Can't resolve './base_protocol' in '/Users/arseniy/Waku/js-waku/packages/sdk/dist/protocols'
Did you mean 'base_protocol.js'?
BREAKING CHANGE: The request './base_protocol' failed to resolve only because it was resolved as fully specified
(probably because the origin is strict EcmaScript Module, e. g. a module with javascript mimetype, a '*.mjs' file, or a '*.js' file where the package.json contains '"type": "module"').
The extension in the request is mandatory for it to be fully specified.
Add the extension to the request.

Solution

Add .js to the failing import
