Broken URLs in preview docs

[tkoskela]

The URL rewriting in #295 does not seem to work as intended. I get in https://ukri-excalibur.github.io/excalibur-tests/preview/PR299/ url's on the main page that look like https://ukri-excalibur.github.io/excalibur-tests/preview/PR299/preview/PR299/install/ ie. the preview/PR299 bit appears twice.

I've been looking at the code but struggling to spot what's the error. This is with PR #294 (before #295):

excalibur-tests/preview/PR294/index.html

Line 1212 in 35ceb1f

<li><a href="https://ukri-excalibur.github.io/excalibur-tests/install/">Installation</a></li>

This is with PR #295:

excalibur-tests/preview/PR295/index.html

Line 1212 in e1c1b1b

<li><a href="https://ukri-excalibur.github.io/excalibur-tests/preview/PR295/install/">Installation</a></li>

I'm really missing what's causing the duplicate preview/PRNNN level. Ok, time to do some debugging.

Ah, wait, it's the second push within the same PR which is messing this up: 771a201#diff-7fd9bc7707206c4dfa2b00b4bf5684de0c820259a4156c27387ab0f72af9315cR1233. I'm very confused.
