Changed 'name' parameter to avoid deployment errors while following the tutorial

[lrottach]

Fixes #1799

Description:

• Changed the 'name' parameter to 'storageAccountName' in the tutorial .md files 01 - 03
• Also changed the parameter in the 01.bicep and 01.json files
• Checked if the commands and examples work as expected

The behaviour, described in the mentioned issue is solved after changing the parameter names.
The following PowerShell command deploys the storage account as expected:

New-AzResourceGroupDeployment -TemplateFile ./main.bicep -ResourceGroupName my-rg -location westus -storageAccountName uniquelogstorage001
