Incorrect URL Displayed in Report of PageSpeed

Bug Report

Describe the bug

The URL displayed in the PageSpeed Insights report comment is truncated to the root domain. The analysis itself runs correctly on the full URL provided, and the generated report content (scores, screenshot) is accurate for the full URL. However, the link text in the comment is incorrect.

To Reproduce

Configure the GitHub Action to run on a URL that includes a path (e.g., a sub-page or a GitHub Pages project site).
My configuration is as follows:

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout repository
        uses: actions/checkout@v4
        with:
          token: ${{ secrets.GITHUB_TOKEN }}

      - name: Create PageSpeed Report
        uses: lowlighter/metrics@latest
        with:
          filename: pagespeed-report.svg
          token: NOT_NEEDED
          base: ""
          plugin_pagespeed: yes
          plugin_pagespeed_screenshot: yes
          plugin_pagespeed_url: https://hanson-hschang.github.io/persona-zola-theme/

Expected behavior
The URL displayed in the report comment should be the exact URL that was analyzed:
https://hanson-hschang.github.io/persona-zola-theme/

Actual behavior
The URL displayed in the report is truncated to the root domain:
https://hanson-hschang.github.io

Screenshots
As shown in the screenshot, the report content is correct for the full URL, but the link at the top is wrong.
