Partial version numbers don't work correctly.

Description:
I've just tried to configure this action to install Go "1.20" - in the hopes that this would then actually install the latest 1.20.x without my needing to be exact. However, what it actually did was install 1.2 instead, which then obviously failed to run the CI pipeline.

Action version:
actions/setup-go@v3

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Tools version:
N/A

Repro steps:
The following Github Actions script:

name: CI

on:
  push:

env:
  GO_VERSION: 1.20

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v3

      - name: Install Go
        uses: actions/setup-go@v3
        with:
          go-version: ${{ env.GO_VERSION }}

Expected behavior:
Ideal would be the latest version of 1.20.x. Acceptable would have been 1.20.0.

Actual behavior:

Hello @sazzer. Thank you for your report. Could you please specify version as go-version: '1.20' ? For now I'm going to close the issue as a duplicate of #326

Aha - yes, reading that one and it makes sense now. Stupid Yaml :)
