DOCSP-39633 fixes mongostat table format

[jwilson-mdb]

DESCRIPTION

Currently, mongostat docs use a table that has incorrect formatting.
This PR migrates that table content to a .. list-table:: directive

STAGING

Thanks @jwilson-mdb! LGTM with one minor nit.
This is subjective. The dividing line between the header row and the regular rows extends substantially past the text and looks a little "weird". I wonder if you modified widths, you could reduce the length of that dividing line?

[jwilson-mdb]

@sarah-olson-mongodb I'll see if I can tweak the widths to make that happen before requesting a merge. It will be a good opportunity to get a bit more comfortable with tables in rst - thanks!

[jwilson-mdb]

@sarah-olson-mongodb I tried to modify the widths but did not see any change in rendering. I checked with some of the other writers and they believe it is the default behavior for .. list-table:: to extend the horizontal line to max width. I also checked other areas of the docs that use .. list-table:: and it seems to confirm that max width is indeed the default behavior.

It may be possible to use an RST simple table/grid table to ditch the horizontal line, but internal docs say the .. list-table:: directive is the "right way" so I will leave it as-is for now.
