JavaScript documentation missing methods

[johanbrandhorst]

Hi!

I noticed the JS generated code documentation (https://developers.google.com/protocol-buffers/docs/reference/javascript-generated#repeated) was missing information about the following methods that are being generated by the latest protoc:

addFooList(): Adds value at specified index in list

And for repeated bytes:

getFooList_asU8(): Gets the array of bytes, with each value converted to Uint8Array
getFooList_asB64(): Gets the array of bytes, with each value converted to Base64 strings

I looked around in this repo and couldn't find anywhere to contribute this, could someone point me in the right direction?

This is somewhat obsolete, but we should amend the add-er documentation to mention the extra argument for insertion.
