Possible Typo in Section “Hardware Required”

[GKalomas]

Consider updating _docs/before-you-start/hardware.md, because of the CAPITALIZED WORDS in the description below.

The subsection titled “Used/existing computing equipment” currently states:

“One of these two computers should be a computer that you do not own (unless purchased brand new), or that HAS spent much time on your home or office network.”

Please consider updating the section to instead state:

“One of these two computers should be a computer that you do not own (unless purchased brand new), or that HAS NOT spent much time on your home or office network.”

Thank you for your consideration and your most diligent and worthwhile efforts in the creation and maintenance of The Glacier Protocol.
