Description of dapr.io/app-max-concurrency default value behavior is wrong

**Describe the issue**
Description of the annotation "dapr.io/app-max-concurrency" default value says "Default value: -1, meaning no concurrency." Default value = -1 seems right, but it does not seem to mean no concurrency, but rather unlimited concurrency or no concurrency limit, as stated in this other page (https://docs.dapr.io/operations/configuration/control-concurrency/), as well as in the code here: https://github.com/dapr/dapr/blob/2adc6ae91b7138d1c7567a2655083698451b9605/cmd/daprd/options/options.go#L150

**URL of the docs**
https://docs.dapr.io/reference/arguments-annotations-overview/

**Expected content**
Correct description of the default concurrency model

**Screenshots**

Open the annotation entry for "dapr.io/app-max-concurrency" on the arguments and annotations overview page, then compare its default-value wording with the control-concurrency documentation and the referenced options.go line. Update the description to accurately explain the default concurrency model and verify the rendered documentation page.
