Add WebGL build preview in PRs using a pipeline

[juans-chainsafe]

Summary
We want to generate a preview of a WebGL build in the PRs so we know if the build is working and we save time for QA tasks

Suggested features or ways to address the summary

• Generate the build and display it on the PR so people can access and use it
• Take in mind, that we need to add the parameters needed for Reown and Web3Auth like project Id in order for them to work

Motivation
This can also be something that we can use to add e2e tests in the build that was generated

Acceptance Criteria

• WebGL build is generated
• Build is displayed in the PR
• Build works and UI is displayed in the browser
• Login and samples works as they will work locally
