Support integer formatting with specifiers D and B

[BCSharp]

Description

Implement proper handling of format specifers "D" and "B".

Related Issue

Resolves #4788

Motivation and Context

I want to be able to format Major, Minor, Patch into one integer so it can be used as Android versionCode.

Format specifier "D" does the job. Format specifier "B" is added, because, why not, it comes for free.

How Has This Been Tested?

Tests have been added to this PR by expanding existing test group GitVersion.Tests.Formatting.NumericFormatterTests.TryFormat_ValidFormats_ReturnsExpectedResult.

Checklist:

• My code follows the code style of this project.
• My change requires a change to the documentation. — Format "D" is already documented, albeit for GitVersion v5.x. Format "B" is undocumented (documented only on Microsoft page)
• I have updated the documentation accordingly.
• I have added tests to cover my changes.
• All new and existing tests passed. — some existing unrelated test fail

Pull request overview

This pull request adds support for Binary (B) and Decimal (D) format specifiers for integer formatting in GitVersion's custom formatting system. The change allows version components to be formatted as binary or zero-padded decimal numbers, complementing the existing Hexadecimal (X) support.

Key changes:

• Extended NumericFormatter to handle "B" and "D" format specifiers alongside the existing "X" format
• Added test cases to verify formatting behavior with precision specifiers (b8, d8, x8)
• Updated documentation to include the new Binary format specifier
