CIP assets: images missing if in folder itself or for CPSs

[rphair]

The current title states my best guess at the reason for the reason staging currently does not build: due to the recent merge of CPS-0010 (cardano-foundation/CIPs#619) and judging by the CIP build script output because of the image pathnames in that GitHub source (https://github.com/cardano-foundation/CIPs/blob/master/CPS-0010/README.md):

Error: Image docs/governance/cardano-problem-statements/no-data-wallet.drawio.png used in docs/governance/cardano-problem-statements/CPS-0010.md not found.
    at async Promise.all (index 0)
[ERROR] Client bundle compiled with errors therefore further build is impossible.

The CPS-0010 source uses the same relative-pathname syntax as successfully used for the images in CIP-0050... so my guess (not looking at the scripts yet; needed to prioritise reporting this problem while still on a bad Internet connection) is that either:

• the prepended /images folder for CIP-0050 allows the script to recognise that there are assets to collect... but doesn't work for images in the CIP folder itself; or:
• whatever rule is used to collect those images is only being run for CIP- documents but not for CPS- documents.

This is a hasty report, with some guesswork, since I'm still travelling almost daily & just wanted to blow the whistle on this, since it's affecting the CI build checking for all PRs open on the Dev Portal. cc @katomm @fill-the-fill @Ryun1
