[nit] Format \t tabs to ' ' 4 spaces in snippets inputs

[Wauplin]

Just an alignment with the rest of the snippets (and inputs snippets).

Suggested by @julien-c but at some point would be good to just run ruff/prettier on the generated snippets so that we don't have to handle this manually.

you could also do the replace in the getSnippets function (plus that would allow the user to specify the indent per tab as an optional param)

.replace(/\t/g, " ".repeat(4));

Yes indeed. I could also make these inputs normal objects and serialize them correctly downstream (as for some other inputs). But short term that was the quickest solution without touching the tooling again.

Will merge this PR "as is" now. CI failure doesn't seem related to my changes.
