[bug] unable to find deployment scope

[ewlidd]

All workflow runs fail using this action with: Exception: [Resolve-TemplateDeploymentScope()] Target scope is resourceGroup, but resourceGroupName property is not present in deploymentConfig.json file

Get-Content -Raw collects the file content as a singular string, instead of an array of lines: https://github.com/climpr/deploy-bicep/blob/008dbaaf4c56908385d1a14a114e9bc1437c3318/src/support-functions.psm1#L195

The subsequent -match here: https://github.com/climpr/deploy-bicep/blob/008dbaaf4c56908385d1a14a114e9bc1437c3318/src/support-functions.psm1#L201 automatically iterates over an array, returning matches, but since $templateFileContent is no longer an array of lines but a singular string it attempts to match the entire template file. It fails to find targetScope in a valid bicep.main file.

Now that I've attempted to write a fix, the pester tests fail https://github.com/climpr/deploy-bicep/actions/runs/11628599292/job/32384035199#step:3:111

Message RuntimeException: Cannot index into a null array. at Resolve-TemplateDeploymentScope, /home/runner/work/deploy-bicep/deploy-bicep/src/support-functions.psm1:203 at <ScriptBlock>, /home/runner/work/deploy-bicep/deploy-bicep/src/Resolve-DeploymentConfig.ps1:64 at <ScriptBlock>, /home/runner/work/deploy-bicep/deploy-bicep/src/tests/Resolve-DeploymentConfig.tests.ps1:22

it appears that $Matches is not being populated after a successful match. This could also be why the above issue described fails. It might be matching successfully but failing to index $Matches at https://github.com/climpr/deploy-bicep/blob/008dbaaf4c56908385d1a14a114e9bc1437c3318/src/support-functions.psm1#L204

Demonstrating $Matches not working on a positive match:
