chore(format): remove end-of-line spaces spotted by remark-lint-no-trailing-spaces

[Danil42Russia]

Closed #1416

Unfortunately, there will still be gaps in some parts of the documentation due to the .remarkignore being ignored. If you don't mind, I would also remove the spaces at the end there.

@anton-trunov, fixed

Thanks! The end-of-line spaces are handled by EditorConfig-compatible editors and plugins, but it's good to explicitly make the formatter do so too.

Regarding ignored files — don't :) The whitepapers there are frequently changed as of now, and their formatting is probably the last thing we'll do after that process ends.

I've formatted touched files once again. Weirdly enough, remark-lint-no-trailing-spaces does not remove the trailing spaces, only warns about them. You might consider removing it from package.json and reverting the package-lock.json changes.

In any case, we'll probably switch to a .mjs config for remark soon, to fine tune it and allow reuse in scripts/. There, I'll make it trim unnecessary spaces :)

Yes, unfortunately, remark-lint-no-trailing-spaces cannot fix errors :(
But I suggest leaving it so that no new errors appear. Then it can be removed later.
