update deprecated setting in devcontainer.json

[deric4]

Use Case

the default shell setting in devcontainer.json is now deprecated:

pdk-templates/moduleroot/.devcontainer/devcontainer.json

Lines 8 to 10 in bd3742c

	"settings": {
	"terminal.integrated.shell.linux": "/bin/bash"
	},

Describe the Solution You Would Like

update the template to something like:

     //...
     "settings": {
          "terminal.integrated.defaultProfile.linux": "bash"
      },
     //...	

Describe Alternatives You've Considered

Completely ignoring the template

Additional Context

Working on applying templates across many modules and would like to standardized the devcontainer configuration. Unfortunately I've been running into quite a few problems but this was seemed trivial enough to request changes upstream 😄

Additionally, I'm unsure if changes here make sense or should or if https://github.com/puppetlabs/pdkgo would be better suited.

thanks!
