* Fix TAGLINE sed delimiter and add apostrophe tagline E2E test

- Switch TAGLINE sed from '#' to '/' delimiter so html_escape'd
  apostrophes (&#39;) don't break the sed expression
- Add standalone-apostrophe Docker service with TAGLINE="It'd rather be fast!"
- Add standaloneApostrophe URL (port 18186) to env.js
- Add E2E test asserting the apostrophe tagline renders correctly

Here's a list of additional environment variables available in this mode:
* __`TITLE`__: Title of your speed test. Default value: `LibreSpeed`
* __`TAGLINE`__: Slogan shown below the heading on the modern frontend (`index-modern.html`). Default value: `No Flash, No Java, No Websockets, No Bullsh*t`
* __`USE_NEW_DESIGN`__: When set to `true`, enables the new modern frontend design. When set to `false` (default), uses the classic design. The design can also be switched using URL parameters (`?design=new` or `?design=old`). Default value: `false`
* __`SERVER_LIST_URL`__: When set, both frontend designs load their server list from this URL instead of the generated or mounted `server-list.json`. This is useful if you want the containerized frontend to consume a remote shared server list.
* __`TELEMETRY`__: Whether to enable telemetry or not. If enabled, you maybe want your data to be persisted. See below. Default value: `false`
