Bicep - Create name (`uniqueString()`) with something constant

[o-l-a-v]

Is your feature request related to a problem? Please describe.

Currently, if deployment name changes, so does the resource names.

keyvault-acmebot/azuredeploy.bicep

Lines 42 to 47 in a24516b

	var functionAppName = 'func-${appNamePrefix}-${substring(uniqueString(resourceGroup().id, deployment().name), 0, 4)}'
	var appServicePlanName = 'plan-${appNamePrefix}-${substring(uniqueString(resourceGroup().id, deployment().name), 0, 4)}'
	var appInsightsName = 'appi-${appNamePrefix}-${substring(uniqueString(resourceGroup().id, deployment().name), 0, 4)}'
	var workspaceName = 'log-${appNamePrefix}-${substring(uniqueString(resourceGroup().id, deployment().name), 0, 4)}'
	var storageAccountName = 'st${uniqueString(resourceGroup().id, deployment().name)}func'
	var keyVaultName = 'kv-${appNamePrefix}-${substring(uniqueString(resourceGroup().id, deployment().name), 0, 4)}'

I prefer creating a deployment name with date and time, instead of reusing the same deployment name. This created the resource above again with a different name.

Describe the solution you'd like

Use something constant but unique when generating the names.

Describe alternatives you've considered

• Remove deployment().id from the lines above.

Additional context

Re-deploy can happen for various reasons, maybe to add and change tags.

I can make a PR if you agree.
