Warning about `.bun-version` not found

[Araxeus]

the action i use is just

- uses: oven-sh/setup-bun@v2

without any parameters, it should just use the latest bun version and not output any errors

the documentation says bun-version-file defaults to undefined

but in reality:

setup-bun/action.yml

Lines 11 to 14 in 339e277

	bun-version-file:
	description: 'The version of Bun to install from file. (e.g. "package.json", ".bun-version", ".tool-versions")'
	default: ".bun-version"
	required: false
