Add pdf+other image preview support to alpine images after Alpine's packaging change

[jessebot]

I'm also creating this PR to add PDF preview support, which doesn't work without the imagemagick-pdf package. This is in reference to #2246 (comment):

But let's also create an issue now (or, better yet, WIP PR) to propose & firm up what others should also be added back in, in a follow-up[1].

[1] We probably want to keep parity. Is there anything that doesn't belong or should we just load all of them back in to mirror the old packaging?

We could also combine this PR with #2246 since we missed the release for 29.0.3 this time anyway. Open to either way, or if I misunderstood, please feel free to give me gentle feedback and I'll remedy what's needed! 🙏

Also open to adding additional packages. svg and pdf are just the file formats that stuck out to me from the beginning.

Per https://git.alpinelinux.org/aports/commit/community/imagemagick/imagemagick.post-upgrade?h=3.19-stable&id=61dce5f6a84d9f96ab7aa6437f12d2845b572ed8 these are our options:

+	* imagemagick support for various modules was split into subpackages.
+	* they autoinstall with the requisite library already installed.
+	* if not already present, install the module you want to use manually:
+	* (prefixed with imagemagick- )
+	* -heic -jpeg -pdf -raw
+	* -svg -tiff -webp -jxl
+	* if you want to exclude the support regardless, use e.g. 'apk add !imagemagick-pdf'

Looking at the formats supported in our Debian images, looks like we do all of these except for jxl. I guess we should include them all save for that one? 🤔

since we missed the release for 29.0.3 this time anyway

Yeah. :-/ Up to you whether to combine them or not. Doesn't matter either way on this side now.

Sure, I'll add the other formats you listed 👍 -except for jxl (what even is jxl 🤷 ).

I'll leave em' separate for now.

I had the exact same reaction. 😆

Ah, crap. It thinks there's a conflict now due to the one line change from the svg PR since that just got merged. 😜 Can you resolve however you prefer and then let's get this one in too.

No problem, that's what I get for not combining the PRs haha :) Let me know if you need anything else!

[joshtrichards]

Wow, all tests passed without having to kick them a few times to re-run. That's rare, but I'll take it!

[jessebot]

Amazing, and I agree very rare 😁
