fix: Show version number with card loading spinner (#1825)

- Closes #1818

**Why add this?**: A repeated pattern is that an issue is fixed in the
card, a new build is released and users will incorrectly believe it's
not yet fixed due to their browser caching the old code. This results in
wasting their time, and my time.

**But it's obnoxious!**: I'm pretty sensitive to this (hence adding
these messages!), so let me know how terrible you find it. You can
disable it with:

```yaml
performance:
  features:
    card_loading_indicator: false
```
