Remove documentation regarding the lack of support for Windows 11 folder names containing spaces

• Remove documentation regarding the lack of support for Windows 11 folder names containing spaces.
• This requires waiting for the release of a new version of vfox. See Route shell commands through PowerShell -EncodedCommand to fix paths with spaces vfox#712 .
• See https://github.com/version-fox/vfox-flutter/blob/fdffc47298604e2557d2a7ff58d1a829ffc2415e/docs/ohos.md .

A Windows home containing a space (C:\Users\John Doe\.vfox) is not supported;
point vfox at a path without spaces with $env:VFOX_HOME = 'D:\vfox'.

• See Support Windows paths containing spaces via PowerShell -EncodedCommmand #32 .

This is a bug in https://github.com/version-fox/vfox itself.
