Generation of Sidebar and Footer does not work when the Sidebar and/or Footer already exist in wiki

[ykuijs]

Details of the scenario you tried and the problem that is occurring

After the change in PR #106 the sidebar is never regenerated once it has been generated once. The code checks if the files exist in the cloned path instead of the WikiSource.

Discussed this with @johlju, he will fix this and submit a PR.

Steps to reproduce the problem

Create a sidebar in the target wiki, don't place a sidebar in the WikiSource and publish a new wiki. The sidebar won't be regenerated in this case.

Expected behavior

The code only regenerates the sidebar and/or footer when it does not exist in the WikiSource

Current behavior

The code never regenerated new sidebar and/or footer after it has been generated once

Suggested solution to the issue

$tempPath should be updated with $Path in the following two lines:

DscResource.DocGenerator/source/Public/Publish-WikiContent.ps1

Lines 131 to 132 in 88d36c7

	New-WikiSidebar -ModuleName $ModuleName -Path $tempPath
	New-WikiFooter -Path $tempPath

The operating system the target node is running

Version and build of PowerShell the target node is running

PSv5.1

Version of the module that was used

v0.10.2

@johlju While you are at it, maybe also update the incorrect examples here:
https://github.com/dsccommunity/DscResource.DocGenerator/blob/main/source/Private/Copy-WikiFolder.ps1#L23
https://github.com/dsccommunity/DscResource.DocGenerator/blob/main/source/Public/Publish-WikiContent.ps1#L51

These are both referring to a WikiSource parameter that doesn't exist (anymore).
