Fixing Typos and minor template updates

[ThorstenLoeschmann]

This pull request primarily includes changes to the 03-Azure/01-03-Infrastructure/08_Migration_Datacenter_Linux directory to enhance the migration process and correct typographical errors in the documentation. The most significant changes are the introduction of a destinationLocation parameter in main.bicep, the change of VM image reference in vm.mig.bicep, and numerous typo corrections in the walkthrough directory.

Changes to the migration process:

• 03-Azure/01-03-Infrastructure/08_Migration_Datacenter_Linux/resources/main.bicep: Introduced a destinationLocation parameter to allow deployments to a different region than the source. The destinationLocation is now used in the destinationRg resource and destination module. [1] [2]
• 03-Azure/01-03-Infrastructure/08_Migration_Datacenter_Linux/resources/vm.mig.bicep: Changed the VM image reference from RedHat RHEL to MicrosoftWindowsServer WindowsServer and added a vmSize parameter to allow changing the VM size. [1] [2]

Typographical corrections in the walkthrough:

• 03-Azure/01-03-Infrastructure/08_Migration_Datacenter_Linux/walkthrough/challenge-1/solution.md: Corrected multiple typographical errors, including misspelled words and incorrect grammar. [1] [2] [3] [4] [5] [6]
• 03-Azure/01-03-Infrastructure/08_Migration_Datacenter_Linux/walkthrough/challenge-2/solution.md: Corrected multiple typographical errors, including misspelled words and incorrect grammar. [1] [2] [3] [4] [5] [6] [7] [8]
