[Orgmode] Small documentation change regarding Agenda View

[Chris Randle]

Hi,

There is, I believe, a small mistake in the documentation for org-mode
v5.19 (although it's been there since the change was made to the code).

PDF Manual page 69, section 10.5, Agenda Views
PDF Reference Card (2/2), Agenda Views, Change display

Both list the "toggle time grid" key as 'g', whereas it's now 'G'.
