Support wildcards in credHelpers (#592)

* Support wildcards in `credHelpers`

With #591 `tart pull` fails when for example you have `ecr-login` set as the default `credsStore` but you try to pull our images from `ghcr.io`.

This change reverts #591 and instead supports regex in `credHelpers`. This is not supported by Docker itself but highly demanded in https://github.com/docker/cli/issues/2928

I think it's fine to support it for Tart.

Additionally this change bumps the minimum host macOS version to Ventura in order to bring `Regex`. Yes, `Regex` only supported in Swift for macOS 13+ 🤦‍♂️I think it's fine in the light of Sonoma release and Tart 2.0.0.

* Removed Monterey mentions from docs

 # License Tiers
 
-When an organization surpasses the 100 CPU cores limit, it is required to obtain a Gold Tier License, which costs \$1000 per month.
+## Free Tier
-Upon reaching a limit of 500 CPU cores, a Platinum Tier License (\$5000 per month) will be required, and for organizations
+
-that exceed 5000 CPU cores, a custom Diamond Tier License (\$1 per core per month) will be necessary.
+By default, when no [license is purchased](#get-the-license), it is assumed that an organization is using a Free Tier license.
+You can find the Free Tier license text in [Tart](https://github.com/cirruslabs/tart/blob/main/LICENSE) and [Orchard](https://github.com/cirruslabs/orchard/blob/main/LICENSE) repositories.
+
+Free Tier license has a 100 CPU core limit for Tart and 4 Orchard Workers limit for Orchard.
+
+??? info "Usage Scenarios Examples"
+
+    Here are a few examples that fit into the free tier:
+
+      - Using Tart on 12 Mac Minis with 8 CPUs each running up to 24 VMs in parallel.
+      - Creating an Orchard cluster of 4 Mac Studio workers with 24 CPUs each.
+
+    Here are a few examples that do not fit into the free tier:
+
+      - Using Tart on 13 Mac Minis with 8 CPUs each.
+      - Creating an Orchard cluster of 5 Mac Minis workers with 8 CPUs each.
+
+## Gold Tier
+
+If an organization wishes to exceed the limits of the Free Tier license, a purchase of the [Gold Tier License](#get-the-license) is required, which costs \$1000 per month.
+
+Gold Tier license has a 500 CPU core limit for Tart and 20 Orchard Workers limit for Orchard.
+
+## Platinum Tier
+
+If an organization wishes to exceed the limits of the Gold Tier license, a purchase of the [Platinum Tier License](#get-the-license) is required, which costs \$5000 per month.
+
+Platinum Tier license has a 5,000 CPU core limit for Tart and 200 Orchard Workers limit for Orchard.
+
+## Diamond Tier
+
+For organizations that wish to exceed the limits of the Platinum Tier license, a purchase of a [custom Diamond Tier License](#get-the-license) is required, which costs \$1 per CPU core per month and gives the ability to run unlimited Orchard Workers.
+
+# Get the license
 
 If your organization is interested in purchasing one of the license tiers, please email [licensing@cirruslabs.org](mailto:licensing@cirruslabs.org).

 ## Mounting directories
 
 To mount a directory, run the VM with the `--dir` argument:
