[Docs] Wording & formatting changes in the Tapping Force Hold section of the Tap Hold page + removed trailing whitespaces (#10391)

* Wording & formatting changes in Tapping Force Hold

The Permissive Hold and the Ignore Mod Tap Interrupt sections were also modified to remove the quotes
around "tapping".

* Removed all trailing whitespaces from tap hold doc

* "it's simply really:" → "it's simple really:"

* "This allows to keep the ability" → "This allows keeping the ability"

Used the gerund form of "to keep" in the Tapping Force Hold section of the Tap Hold docs.

-When the user holds a key after tap, this repeats the tapped key rather to hold a modifier key.  This allows to use auto repeat for the tapped key.  
+When the user holds a key after tapping it, the tapping function is repeated by default, rather than activating the hold function. This allows keeping the ability to auto-repeat the tapping function of a dual-role key. `TAPPING_FORCE_HOLD` removes that ability to let the user activate the hold function instead, in the case of holding the dual-role key after having tapped it.
 
 Example:
 
-- SFT_T(KC_A) Down
+- `SFT_T(KC_A)` Down
-- SFT_T(KC_A) Up
+- `SFT_T(KC_A)` Up
-- SFT_T(KC_A) Down
+- `SFT_T(KC_A)` Down
-- wait more than tapping term...
+- wait until the tapping term expires...
-- SFT_T(KC_A) Up
+- `SFT_T(KC_A)` Up
 
 With default settings, `a` will be sent on the first release, then `a` will be sent on the second press allowing the computer to trigger its auto repeat function.
 
 With `TAPPING_FORCE_HOLD`, the second press will be interpreted as a Shift, allowing to use it as a modifier shortly after having used it as a tap.

-Well, it's simply really: customization.  But specifically, it depends on how your keyboard is wired up.  For instance, if each row is actually using a row in the keyboard's matrix, then it may be simpler to use `if (record->event.row == 3)` instead of checking a whole bunch of keycodes.  Which is especially good for those people using the Tap Hold type keys on the home row. So you could fine tune those to not interfere with your normal typing.
