small shigella updates, take 2

[kapsakcj]

Opened a new PR so I don't pollute the commit history with my old PR and failed attempt at rebasing.

Need to update CI and test once more in Terra, but should be ready for review shortly

🛠️ Changes Being Made

• updated default shigatyper docker image to v2.0.5 (from 2.0.3) hosted on GAR
• added optional Integer input memory for shigatyper task.
• exposed optional String input shigatyper_docker_image in merlin_magic subwf so that user has the ability to change via TheiaProk workflows in Terra

🧠 Context and Rationale

Previously the user was not able to adjust the shigatyper docker image, meaning they were stuck with the previous version that had a bug with Shigella flexneri serotyping. The updated version 2.0.5 fixes this bug.
