Prefer pretty permalinks like WP install does (#1832)

## Motivation for the change, related issues

The WordPress installation process defaults to pretty permalinks if it
can enable them and get a valid response from a loopback request.
Unfortunately, at the time we run the WP installation process in
Playground, the PHP request handler has not yet been put into place to
handle those requests.

In addition, even if the request handler was in place in time, @adamziel
[mentioned](#1644 (comment)):

for a dramatic installation speedup in web browsers

As a workaround, we can manually set the `permalink_structure` as part
of WordPress installation within `bootWordPress()`.

Closes #1644

## Implementation details

Manually sets the `permalink_structure` as part of WordPress
installation within `bootWordPress()`.

## Testing Instructions (or ideally a Blueprint)

Manual testing after creating nightly WP build which was pre-installed
using this logic using Playground CLI. Loading the nightly build locally
shows permalinks enabled.
