update resolves in parallel under the super shell

Building on #9270 (parallel dependency resolution for non-interactive runs), update now also resolves in parallel under the interactive super shell. Previously sbt let coursier draw its own per-module progress bars there, and those bars cannot be rendered from more than one module at once, so resolution was serialized one module at a time. sbt now suppresses coursier's bars and renders a single aggregate progress line at the task level instead, e.g.:

Updating 18 modules, 240 artifacts, 31.0 MiB

so resolution can run concurrently across modules. Setting csrLogger := Some(...) opts out: your logger is used instead, and coursier's behavior is unchanged.

This is the first step of #5627. Per-module status lines (which would add a status field to ProgressItem) remain a possible follow-up.
