docs: fix typos
After Gmail called out the typo I fixed on
532d89a866, I've decided to paste the
whole man page into Google docs and check what other issues it would
spot.

I know, it sounds silly, but I've just spent the last hour and a half
going over each one of them and fixing everything which was a true
finding and non-controversial.

Closes #17480

--hsts

Enable HSTS for the transfer. If the filename points to an existing HSTS cache file, that is used. After a completed transfer, the cache is saved to the filename again if it has been modified.

If curl is told to use HTTP:// for a transfer involving a hostname that exists in the HSTS cache, it upgrades the transfer to use HTTPS. Each HSTS cache entry has an individual lifetime after which the upgrade is no longer performed.

Specify a "" filename (zero length) to avoid loading/saving and make curl just handle HSTS in memory.

If this option is used several times, curl loads contents from all the files but the last one is used for saving.
