Bump System.Text.RegularExpressions to 4.3.1

[igor-toporet]

Currently, when using Wolverine, dotnet build emits the following warning:

warning NU1903:
Package 'System.Text.RegularExpressions' 4.3.0 has a known high severity vulnerability,
https://github.com/advisories/GHSA-cmhx-cq75-c4mj    

See GHSA-cmhx-cq75-c4mj for details.

Using the following command

dotnet nuget why System.Text.RegularExpressions

I was able to trace it to the following graph:

Project '<masked>' has the following dependency graph(s) for 'System.Text.RegularExpressions':

  [net9.0]
   │
   ├─ <masked> (v1.0.0)
   │  └─ WolverineFx.Marten (v3.5.0)
   │     └─ WolverineFx.Postgresql (v3.5.0)
   │        └─ WolverineFx.RDBMS (v3.5.0)
   │           └─ System.Data.Common (v4.3.0)
   │              └─ System.Text.RegularExpressions (v4.3.0)
   ...

I checked the https://www.nuget.org/packages/System.Data.Common but it does not have a patched version after v4.3.0.

So the only option I can see is to reference it directly in WolverineFx.RDBMS.

I hope you find this valuable enough and meeting the repository standards.
