Bump epidatr & epipredict versions, update due to breaking changes

Bump versions, update renv.lock.

Adjust for breaking changes:
- Some obvious renames.
- Replace both `pivot_quantiles` and `unnest` `pivot_wider` patterns to
  `pivot_quantiles_wider`.
- Fix some `epi_recipe` and `frosting` printing that doesn't play well with
  knitr now.

Update _freeze files where a first pass visual diff identified
"real" differences rather than just a tiny visual offset.
