Tag without version drop semver to zeros

Steps to Reproduce

run powershell with net7.0 dotnet cli

dotnet new globaljson --sdk-version=7.0.401 --force
mkdir testproject
cd testproject
dotnet new console
git init
wget -O .gitignore https://raw.githubusercontent.com/github/gitignore/main/VisualStudio.gitignore
((Get-Content -path testproject.csproj -Raw) -replace '</Project>','') | Set-Content -Path testproject.csproj
Add-Content -Path testproject.csproj -Value '    <ItemGroup>'
Add-Content -Path testproject.csproj -Value '       <PackageReference Include="GitInfo" Version="3.3.3">'
Add-Content -Path testproject.csproj -Value '            <PrivateAssets>all</PrivateAssets>'
Add-Content -Path testproject.csproj -Value '            <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>'
Add-Content -Path testproject.csproj -Value '        </PackageReference>'
Add-Content -Path testproject.csproj -Value '    </ItemGroup>'
Add-Content -Path testproject.csproj -Value '</Project>'
dotnet restore
git add *
git commit -m "init"
git tag -a v0.1 -m "init"
dotnet run
cat ./obj/Debug/net7.0/testproject.AssemblyInfo.cs

output contains

[assembly: System.Reflection.AssemblyVersionAttribute("0.1.0.0")]

Add-Content -Path testproject.csproj -Value ' '
git add *
git commit -m "init 2"
git tag -a error -m "version reset"
dotnet run
cat ./obj/Debug/net7.0/testproject.AssemblyInfo.cs

output contains

[assembly: System.Reflection.AssemblyVersionAttribute("0.0.2.0")]

but must get read first right tag with version from commits below

Expected Behavior

[assembly: System.Reflection.AssemblyVersionAttribute("0.1.2.0")]

Version Info

GitInfo 3.3.3

As documented in the targets and readme:

$(GitTagRegex): regular expression used with git describe to filter the tags to consider for base version lookup. Defaults to * (all).

You could default it to $(GitBaseVersionRegex) via a Directory.Build.targets or use its value (or a simplified version):

    <GitBaseVersionRegex Condition="'$(GitBaseVersionRegex)' == ''">v?(?&lt;MAJOR&gt;\d+)\.(?&lt;MINOR&gt;\d+)(?:\-(?&lt;LABEL&gt;[\dA-Za-z\-\.]+))?$|^v?(?&lt;MAJOR&gt;\d+)\.(?&lt;MINOR&gt;\d+)\.(?&lt;PATCH&gt;\d+)(?:\-(?&lt;LABEL&gt;[\dA-Za-z\-\.]+))?$|^(?&lt;LABEL&gt;[\dA-Za-z\-\.]+)\-v?(?&lt;MAJOR&gt;\d+)\.(?&lt;MINOR&gt;\d+)\.(?&lt;PATCH&gt;\d+)$</GitBaseVersionRegex>

For example:

<PropertyGroup>
   <GitTagRegex>v?\d+\.\d+\.\d?</GitTagRegex>
</PropertyGroup>

In this case, the targets would run git describe --tags --match=v?\d+\.\d+\.\d? --abbrev=0
