chore: Fix error message from newer svelte dependencies.

Description

Fix error message from newer svelte dependencies.

The error message was:

Error: Argument of type '{ "bind:value": string; id: string; type: string; class: string; placeholder: string; accesskey: string | null; "on:keydown": (e: KeyboardEvent) => void; "on:paste": () => void; "on:drop": () => void; }' is not assignable to parameter of type 'HTMLProps<"textarea", HTMLAttributes<any>>'.
  Object literal may only specify known properties, and '"type"' does not exist in type 'HTMLProps<"textarea", HTMLAttributes<any>>'. (ts)
                id="description"
                type="text"
                class="tasks-modal-description"

They are complaining about the 'type="text"' line.

When I delete that line and test the Create or edit task modal, the Description field still works fine.

I believe that this line was a hangover from an earlier version of this code where the Description field was a one-line field.

Motivation and Context

See the initial build failures in:

• build(deps-dev): bump @tsconfig/svelte from 3.0.0 to 5.0.0 #2077
• chore(deps-dev): bump svelte-check from 2.10.3 to 3.4.6 #2118

How has this been tested?

• By building the Tasks plugin locally, having manually applied the version updates from the two PRs above
• And then testing that editing the Description field still works.
