Context

Compile floor is currently Go 1.19. This ticket is for collecting justifications for bumping forward.

Motivators (add as they come up)

• (1.21+) tls.AlertError — extends topology.wrapConnectionError
  deny-list per CMAP. Tracked under GODRIVER-3906.
• (1.25+) Can stop ignoring testcontainer-go updates, e.g. https://github.com/mongodb/mongo-go-driver/pull/2384. Re-open this PR if we bump to a Go version > 1.25.0
• Newer go versions limit the number of dependencies users will have to manually upgrade via minimal version selection since dependabot can update them for us to transitively pass to users.
