Feature request: Re-order the three main feeds under Communities in Posts tab

**Is your feature request related to a problem? Please describe.**

The default position/page of the Posts tab is the Communities list, which has the three main feeds at its top:

- Subscriptions
- All
- Local

Personally, I like looking at my Subscriptions, then Local, to see what's going on my server in the Communities that I don't explicitly subscribe to, and then, finally I look at All, to see what's up in the wider Fediverse/Lemmy.

As such, the order of this list is somewhat contrary to my flow, and I'd like the ability to change the order, or at least have the default order changed.

**Describe the solution you'd like**

Change the order of the main Feeds at the top of the Communities page as follows:

- Subscriptions
- Local
- All

**Describe alternatives you've considered**

In writing this feature request, I noticed my logic hinges on the fact that I mainly(but not exclusively) subscribe to Communities on my home server, which means that my perception of the Fediverse/Lemmy hierarchy, as related to Feeds, looks like this:

- I made an active choice to Subscribe to certain Communities, most of which (but not all) are part of my Local server, which is part of the wider (All) Fediverse.

or,

- Subscriptions is a list of my own personal choices, thus most important (top position).
- When joining Lemmy, I made an active choice about which server (Local) I would attach my account to (second position), for one reason or the other.
- Everything else (All) is what I gain access to by having a Lemmy account, which I can peruse when my Subscriptions or Local feeds run dry, or I'm feeling adventurous (third position).

This may not be true for all (or, indeed, most) users, so my reasoning for wanting the list re-ordered might not be all that applicable to the Voyager userbase in general.

However, I do think that many Lemmy users chose their particular home server deliberately (possibly based on interests, political leanings, hobbies, etc.), and that might mean that their interest in their local server supersedes their interest in Lemmy as a whole, it nothing else then to a slightly higher degree. Which means my list hierarchy suggestion might not be too far off.

**Additional context**
None at present.
