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

--limit-rate

Specify the maximum transfer rate you want curl to use - for both downloads and uploads. This feature is useful if you have a limited pipe and you would like your transfer not to use your entire bandwidth. To make it slower than it otherwise would be.

The given speed is measured in bytes/second, unless a suffix is appended. Appending 'k' or 'K' counts the number as kilobytes, 'm' or 'M' makes it megabytes, while 'g' or 'G' makes it gigabytes. The suffixes (k, M, G, T, P) are 1024 based. For example 1k is 1024. Examples: 200K, 3m and 1G.

The rate limiting logic works on averaging the transfer speed to no more than the set threshold over a period of multiple seconds.

If you also use the --speed-limit option, that option takes precedence and might cripple the rate-limiting slightly, to help keep the speed-limit logic working.
