📝 Update Presets page to use Preset instead of Override

Loop does not have a baked-in Workout Preset.
Rename "Workout Targets" section as "Creating a Custom Preset"
that explains how to create a custom Workout Preset.

-Your Loop has two override targets that you can set; *Pre-meal* and *Workout*. When activated, these targets will "override" or take the place of your usual correction range and therefore will affect Loop's decisions about insulin delivery.
+Your Loop has a built-in preset you can activate: *`Pre-meal`*.   
+You can also define custom presets, like a *Workout* preset.
 
-You can set the value for these override targets from the Correction Range area of Loop settings. Generally speaking, pre-meal targets are set to value(s) lower than your correction range, and workout targets are set to value(s) greater than your correction range. *Loop* will indicate that an override target is active by showing a darker blue bar on the blood glucose chart showing the duration and location of the target.

+You can activate the `Pre-Meal` preset by pressing the icon that looks like a timer :material-camera-timer: between a f​ork and a knife :fontawesome-solid-utensils:.
+
+It  will stay active for:  
 
 * one hour, or
 * until carbs are entered, or 
 * until the pre-meal target is manually cancelled by pressing the icon again.
 
-Pre-meal target will automatically end when one of those three things happens, whichever comes first will end the pre-meal target.

-The original intent of the pre-meal target was to help give a gentle, easy pre-bolus effect to help lessen a post-meal blood glucose spike. By lowering your Loop's target going into a meal, you can get a "pre-bolus" effect because Loop will aim for that lower target and thus tend to set a little more aggressive insulin delivery while the target is active. Loop will recognize the "extra" insulin that has been delivered while pre-meal is active, and Loop will smartly take that into account when it is finally time to recommend a bolus at meal entry time.

-Pre-meal target won't replace the utility of a true pre-bolus in most situations, but it can be useful in many situations beyond simply helping meals. This lower target can help Loop be more aggressive:

-## Workout Targets
+## Creating a Custom Preset
 
-The workout target, when activated, will give a duration choice of 1 hour, 2 hours, or indefinitely.  The workout target set greater than your usual correction range is useful to help in situations where Loop needs to be *less* aggressive with insulin delivery. The most common use of the workout target is to set it in advance and during exercise to help minimize IOB going into a workout. While the name is a hint to the most common timing of this override's use, there are other times when it can be helpful, such as:

-* Helping during illness which tends to lower blood glucose or increase insulin sensitivity
