Using dotnet-version: 7.0.x installs .NET 8.0.x instead onf 7.0.x

[MikeSchulze]

Description:
I added the setup-dotnet action to install Net 7.0.x if is required, but it installs the NET 8.0.x

Task version:
actions/setup-dotnet@v4

Platform:

• Ubuntu 22.04.5
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Repro steps:

    - name: 'Setup .NET SDK'
      uses: actions/setup-dotnet@v4
      with:
        dotnet-version: '7.0.x'

Expected behavior:
I used a matrix and caching action behind, but the installation looks wrong.

Actual behavior:

Run sdk_version=$(echo "net7.0" | sed 's/^net\([0-9]\.[0-9]\)$/\1.x/')
Using .NET version: '7.0.x'
Run actions/setup-dotnet@v4
  with:
    dotnet-version: 7.0.x
    cache: false
  env:
    CACHE_NAME: Linux-Godot_v4.2-stable-net7.0
    RUN_GDSCRIPT_TESTS: false
    GDUNIT_VERSION: master
    SDK_VERSION: 7.0.x
