feat: open external sidebar links in new tab

[jarrensj]

Add target="_blank" and rel="noopener noreferrer" to all external links in the author sidebar

I have mixed feelings about target="_blank" since I tend to just open in a new tab by default; however, note that rel="noopener" is a bit redundant these days since modern browsers add it by default to <a> elements.

all good, just felt like I kept clicking sidebar social links and then losing the original page I was on so I was hoping it would open a new tab instead but I think whatever you think is best for the template works for me!

I normally just anticipate it opening in a new tab so I don't often then I need to intentionally right-click to open into a new tab. We can close this PR though if you think it's not needed!

Let me know if I should close this (or keep but remove noopener) and I can get that done!
