Pre-flight checklist

• I have read the Contributing Guidelines on pull requests.
• Commit messages follow the conventional commits spec
• If this is a code change: I have written unit tests.
• If this changes code in a published package: I have run pnpm changeset to create a changeset JSON document appropriate for this change.

Motivation

This PR contains fixes for #1330 issue. The main reason why passkey did not work with BitWarden was because they do not follow standard format for webauthn credentials in which they used data format of Uint8Array instead of ArrayBuffer. However they can be easily convert-able so in this PR I have implemented logic to do the conversion.

Test Plan

On https://github.com/near/fast-auth-signer/ repo, run it locally with commend yarn && NETWORK_ID=testnet yarn run start --https (Bitwarden only works with https)
On new Chrome browser profile, install Bitwarden chrome extension package.
manually navigate to localhost:3000/create-account and try to create an account.
(At this point, you should be able to replicate the issues)

Apply the above change directly to source code. (There is issues with setting up yarn link/npm link between these two projects)

I have confirm that above change has resolved the issue and was able to conduct create key and get keys without error.

The code looks good, I've left only a few minor styling and wording remarks
