Publish-PSResource does not properly read #PSScriptInfo if value is separated by newline

[tmarvin-repay]

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.

Steps to reproduce

Publish-PSResource does not properly parse the PSScriptInfo comment header if the key (ex: .VERSION) is separated from the value by a newline.

For example this header works:

<#PSScriptInfo
.VERSION 1.0.0

.GUID a2777fce-98e1-4e26-b0df-d698a755c259

.AUTHOR	Test Author

.COMPANYNAME Test Company

.COPYRIGHT Test CopyRight

.PROJECTURI https://google.com/
#>

<#
.DESCRIPTION
 A verbose description!
#>
Param()

However this does not.

<#PSScriptInfo
.VERSION
 1.0.0

.GUID
 a2777fce-98e1-4e26-b0df-d698a755c259

.AUTHOR
 Test Author

.COMPANYNAME
 Test Company

.COPYRIGHT
 Test CopyRight

.PROJECTURI
 https://google.com/
#>

<#
.DESCRIPTION
 test
#>
Param()

It seems inconsistent to me that the description can be separated by a newline but that the other parameters cannot.

Expected behavior

The script header is parsed successfully and a nuget package is produced regardless of the whitespace after a comment header.

Actual behavior

An error is generated with some variation of `No version was provided in the script metadata. Script metadata must specify a version, author, description, and Guid.` (depends on which is missing [version, author, Guid]).
