[CentOS-docs] Typo on "AdditionalResources/HardwareList" page

[Timothy Lee]

Dear all,

Under "Where to turn first" section, inside the paragraph just after the 
bullet points, the string "read,write Default" has been mistakenly 
inserted.  The sentence:

    ... complete systems that are certifieread,write Defaultd for
    running under RHEL ...

should read:

    ... complete systems that are certified for running under RHEL ...

Regards,
Timothy Lee
