Add WebGL build preview in PRs using a pipeline

**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
