Webp conversion is causing static build to fail

[russss]

The static build is now failing

0.527 Error! Could not process file /usr/share/nginx/emf-static/static/images/2018_post-d4ab795330bb9644b142d13273fec618.jpg
0.527 Error! Cannot read input picture file '/usr/share/nginx/emf-static/static/images/2018_post-d4ab795330bb9644b142d13273fec618.jpg'

This has presumably been caused by an upstream Alpine update.

This error is being reported by cwebp and isn't related to that specific jpeg. I don't know if it's happening with all jpegs but it's certainly more than one of them (and not all of them are progressive jpegs like 2018_post.jpg).

The cwebp commandline still reports that it's capable of handling JPEGs.

You can reproduce by doing a docker build . in docker/static.

I don't think this caused by cwebp. 2018_post.jpg in the latest website image is full of Unicode replacement characters (ef bf bd):

Seems to apply to all images.

Also bad:

i=ghcr.io/emfcamp/website@sha256:853eeb6d9050cd2b772bff61617f10531cf5d496d68251422228cd3f2a9a9fc2
docker pull $i && docker run --rm --entrypoint=bash $i -c 'cat /app/static/images/2018_post.jpg'|xxd|head

Bad i=ghcr.io/emfcamp/website@sha256:9598465ee8a9b74302eb54b98914fb4c23f7a6e70d81341ad51efa99837cf2de Good i=ghcr.io/emfcamp/website@sha256:da707501a4bc7c03c537040ccf979dd6e72eed2fc10241b5801440ad0c73e1a3 Good i=ghcr.io/emfcamp/website@sha256:de8dc823e49a2eb9d12d2d0739d70458debc9d8dda12ff592aaee5ffe109dbf8

So it broke with https://github.com/emfcamp/Website/actions/runs/9863319190/job/27235909312, which was the first since adding pump and also this base image build https://github.com/emfcamp/Website/actions/runs/9738746855.

Maybe a change between pump 2.0 and 3.0? Unlikely are there are basically no changes.

Caused by Default stream encoding to UTF-8, included in #1735. I can't work out why bumping braces required bumping gulp in the first place but it is the first gulp release in 5 years and included a list of breaking changes so we probably can't grumble.
