chore: Improve GitHub issue templates to align with SqlServerDsc

Summary

Align the GitHub issue templates in this repository with the conventions used by SqlServerDsc, which serves as the reference implementation for DSC Community module issue templates.

Current state

The .github/ISSUE_TEMPLATE/ folder currently contains files without numeric prefixes, resulting in inconsistent ordering in the GitHub UI.

Desired state

Rename and align the existing files to match the SqlServerDsc naming convention (numeric prefixes ensure a consistent ordering in the GitHub UI):

Tasks

• Rename General.md → 01_general.md
• Rename Resource_proposal.yml → 02_resource_proposal.yml
• Rename Problem_with_resource.yml → 03_problem_with_resource.yml
• Review each template body against its SqlServerDsc counterpart and apply any improvements to wording, field labels, or descriptions
• Verify config.yml contact links are still current

References

• SqlServerDsc ISSUE_TEMPLATE folder: https://github.com/dsccommunity/SqlServerDsc/tree/main/.github/ISSUE_TEMPLATE

Start in .github/ISSUE_TEMPLATE/ and compare General.md, Resource_proposal.yml, and Problem_with_resource.yml with the corresponding SqlServerDsc templates. Check config.yml contact links as well. Done means the three files use the requested numeric names, their contents reflect the reference conventions, and the contact links remain current.
