Option for parentheses around equation numbers reference in addition to `eq-prefix`

Discussed in https://github.com/quarto-dev/quarto-cli/discussions/2413

In certain journals it is common to format references to equations like Eq. (1.1) with parentheses around the equation number. Quarto supports modifying Eq. with eq-prefix, but would it be possible to either

1. Add a parameter similar to eq-prefix that allows one to customize the reference further, and/or
2. Ensure that, when compiled to PDF, \eqref gets used rather than \ref for equation references. This would require amsmath I suppose, but would automatically add parentheses and permit further customization.

Thanks!
