This changes makes it so that we output the empty string for Format
when there is no data. It turns out there are many places in the code
where we have such handling, but in a way that would break the JSON
formatter (since we'd output nothing on stdout or text rather than
`[]`/`null`).
Refactors the CLI to create the `*codersdk.Client` in the handlers. This is groundwork for changing the `rootCmd.InitClient()` to use the new `ClientOption`s.
It also improves variable locality, scoping the Client to the handler. This makes misuse less likely and reduces the memory allocations to just the command being executed, rather than allocating a Client for every command regardless of whether it is executed.
## Description
This PR improves the `coder templates presets` and `coder create` CLI
commands to include preset descriptions.
## Changes
* Added a `description` column to the `coder templates presets list` CLI
command.
* Fixed the `-o json` output for `coder templates presets list` to
correctly include and format data.
* Updated the `coder create` CLI command to display the preset's
description in the selection menu.

## Description
This PR introduces a new `list presets` command to display the presets
associated with a given template.
By default, it displays the presets for the template's active version,
unless a `--template-version` flag is provided.
## Changes
* Added a new `list presets` command under `coder templates presets` to
display presets associated with a template.
* By default, the command lists presets from the template’s active
version.
* Users can override the default behavior by providing the
`--template-version` flag to target a specific version.
