docs: broken link to example vs-code settings.json config for zarf yaml schema validation

[JoeHCQ1]

This link is broken: https://github.com/defenseunicorns/uds-common/blob/main/docs/development-ide-configuration.md?plain=1#L19. Note that link shows up twice in the file.

good catch! The file that is linked to is not .vscode/settings.json relative to the file its ../.vscode/settings.json. Labelled this as good first issue. Similarly, the way the link is named could probably be adapted to be more accessible for screen reader/etc. For example, [example](.vscode/settings.json) could better identify what the link is something like [example vscode settings file]
