Implement UI build pipeline

[DaltheCow]

Builds would live at:
pr builds - neuralmagic.github.io/guidellm/ui/pr/12
dev - neuralmagic.github.io/guidellm/ui/dev
staging/release-candidate - neuralmagic.github.io/guidellm/ui/release/v1.0.0 or .../ui/release/latest
production/release - neuralmagic.github.io/guidellm/ui/v1.0.0 or .../ui/latest

PR builds will include mocked data, view example in comments below. All other builds currently will be blank slates, waiting to be pulled down and used to generate an html report.
