docs: fix graphic in safari (#43502)

Fixes that the "Loved by millions" graphic doesn't look correctly on Safari.

Note that this fix is somewhat repetitive, but I couldn't find a better one. These are the other things I tried:
* Setting units on the size of `#angular-logo`.
* Setting the size of `#angular-logo` inside the `style` tag.
* Setting the size with inline styles.

Fixes #43498.
