[ISSUE]: Formatting does not support format specifier "D" #4788
Description

GitVersion package

Operating system

What are you seeing?
One of the commandline options is /format, which allows to output formatted variables. From the output of dotnet-gitversion /h:
/format Used in conjunction with /output json, will output a format
containing version variables.
Supports C# format strings - see [Format Strings](/docs/reference/custom-formatting) for details.
E.g. /output json /format {SemVer} - will output `1.2.3+beta.4`
/output json /format {Major}.{Minor} - will output `1.2`
There is no /docs/reference/custom-formatting describing Format Strings for v6.x, but for v5.12.0 is seems to be a subset of Standard .NET Format Strings.
Unfortunately, this does not work on v6 with format the decimal format string "D".
What is expected?
If variable Major is 1 and Minor is 2, running
dotnet-gitversion /output json /format "{Major}.{Minor:D2}"
should produce
102
Steps to Reproduce
C:\my-project> dotnet-gitversion /output json /format "{Major}.{Minor:D2}"
