Update templates

Description

Resolves feedback in issue #198.

The renaming will be a breaking change however since the release has not been made yet and includes additional breaking changes - now is the correct time to make this change.

1. This PR renames the variables to remove "Default"
2. Add's additional "Most Compatible" template
3. Add's a notice to the "MicrosoftAndOptionRoms.toml" indicating that the template is not yet recommended due to lack of saturation in the ecosystem for the Option ROM CA signing.

Templates/MicrosoftAndOptionRoms.toml:2

• [nitpick] The template header name appears inconsistent with the file name 'MicrosoftAndOptionRoms.toml' and its intended Option ROM usage. Consider revising the template name to better reflect its purpose.

# Template Name: Secure Desktop – Microsoft Only

Templates/MicrosoftAndThirdParty.toml:39

• [nitpick] The help text references 'MicrosoftOnlyDefaults', which is inconsistent with the new naming convention. Updating this description for clarity would improve consistency.

help = "Contains 2023 Microsoft and UEFI third party certificates to verify binaries before execution. More compatible than MicrosoftOnlyDefaults."
