Fixes an issue with loading static content paths which contain wildcard characters

Description of the Change

Fixes an issue with loading static content paths which contain wildcard characters. When loading singular files, Pode will now auto-escape wildcard characters like * and [ in paths.

At times, this escaping might not be required so a new -NoEscape switch has been added onto the relevant functions.

Escaping is done via [WildcardPattern]::Escape()

Examples

# the following path will now work, and be escaped accordingly
Set-PodeResponseAttachment -Path './[metadata].json'

# if the path is already escaped, -NoEscape can be used
Set-PodeResponseAttachment -Path './`[metadata`].json' -NoEscape
