Boolean inputs are not actually booleans

Problem

>[!NOTE] > Although this has been fixed, see also: > - #2238 Describe the bug Boolean type inputs do not work as expected; they are strings instead of booleans, even when surrounded by `${{ }}` (e.g. in a step's `if` condition). To Reproduce Steps to reproduce the behavior: Run this workflow using the workflow dispatch, with the foo input checkbox not ticked: [code block] Expected behavior When the input is `false`, the `Run if foo` step should be skipped , and the `Don't run if foo` step should run. Runner Version and Platform Version of your runner? `2.284.0` OS of the machine running the runner? `ubuntu-latest (20.04.3)` What's not working? The value of `github.event.inputs.foo` is `false`, yet the `Run if foo` step runs and the `Don't run if foo` step is skipped. Additional context It is the same for a string input type or boolean input type (https://github.blog/changelog/2021-11-10-github-actions-input-types-for-manual-workflows/). Only `if: ${{ github.event.inputs.foo == 'true' }}` works. So the input must be being treated as a string. This goes against what the documentation says at https://docs.github.com/en/actions/learn-github-actions/expressions#about-expressions: >...evaluate an expression rather than treat it as a string. > >`${{ <expression> }}`
