Upgrades to slog v3 which includes a small, but backward incompatible API change to the acceptible call arguments when logging. This change allows us to verify via compile time type checking that arguments are correct and won't cause a panic, as was possible in slog v1, which this replaces (v2 was tagged but never used in coder/coder).
It also updates dependencies that also use slog and were updated.
I've left the `aibridge` dependency as a commit SHA, under the assumption that the team there (cc @pawbana @dannykopping ) will tag and update the dependency soon and on their own schedule.
Other dependencies, I pushed new tags.
## Overview
This change promotes the tasks CLI commands from `coder exp task` to
`coder task`, marking them as generally available (GA).
## Migration
Users will need to update their scripts from:
```shell
coder exp task create "my task"
```
To:
```shell
coder task create "my task"
```
