Remove explicit return types rule

[hannahblair]

Description

I'm proposing we remove eslint's explicit function return types rule. We have quite a few of these errors around our repo (e.g Dataset.svelte) but can't fix these if the function is inline because Svelte can't parse non-standard JS expressions in the markup of the file without adding an external transpiler into the mix, it can only do so in the <script />. The only way of resolving the error is moving the func to the <script /> but this isn't ideal, and I think we should just remove this rule to tidy up our errors. This is a known limitation. Also a discussion around it here.

Open to discussion around this!

We don't need to remove the rule, just play with the options I've fixed this in #5074 by tweaking this rule:

gradio/.config/eslint.config.js

Lines 38 to 41 in de24ec6

	"@typescript-eslint/explicit-function-return-type": [
	"error",
	{ allowExpressions: true }
	],
