docs: restructure installation instructions to be per platform

Browse source 
The only overlap between the instructions for Linux, Mac, and Windows
is the `cargo install` step, so let's instead split it up so it's easy
for the user to skip to the relevant part, especially as we add more
platform-specific instructions.

I promoted some sections to one level higher sections to try to
clarify that the initial configuration and the command-line completion
applies to all platforms.

## Installation
If you're on Mac, you may need to run some or all of these:
```shell script
xcode-select --install
brew install openssl
brew install pkg-config
export PKG_CONFIG_PATH="/opt/homebrew/opt/openssl@3/lib/pkgconfig"
```
### Linux
Now run this (regardless of platform):
On most distributions, you'll need to install from source.
#### From source
Run:
```shell script
cargo install --git https://github.com/martinvonz/jj.git
```
You may also want to configure your name and email so commits are made in your
name. Create a file at `<config dir>/jj/config.toml` (where `<config dir>` is
`${XDG_CONFIG_HOME}` or `~/.config/` on Linux, `~/Library/Application Support/`
on macOS, and `~\AppData\Roaming\` on Windows) or `~/.jjconfig` and make it
look something like this:
```shell script
$ cat ~/.jjconfig
[user]
name = "Martin von Zweigbergk"
email = "martinvonz@google.com"
```
### Command-line completion
To set up command-line completion, source the output of
`jj debug completion --bash/--zsh/--fish`. Exactly how to source it depends on
your shell.
#### Bash
```shell script
source <(jj debug completion) # --bash is the default
```
#### Zsh
```shell script
autoload -U compinit
compinit
source <(jj debug completion --zsh | sed '$d') # remove the last line
compdef _jj jj
```
#### Fish
```shell script
jj debug completion --fish | source
```
### Nix OS
#### Nix OS
If you're on Nix OS you can use the flake for this repository.
For example, if you want to run `jj` loaded from the flake, use:

### Mac
You may need to run some or all of these:
```shell script
xcode-select --install
brew install openssl
brew install pkg-config
export PKG_CONFIG_PATH="/opt/homebrew/opt/openssl@3/lib/pkgconfig"
```
Now run:
```shell script
cargo install --git https://github.com/martinvonz/jj.git
```
### Windows
Run:
```shell script
cargo install --git https://github.com/martinvonz/jj.git
```
## Initial configuration
You may want to configure your name and email so commits are made in your name.
Create a file at `<config dir>/jj/config.toml` (where `<config dir>` is
`${XDG_CONFIG_HOME}` or `~/.config/` on Linux, `~/Library/Application Support/`
on macOS, and `~\AppData\Roaming\` on Windows) or `~/.jjconfig` and make it
look something like this:
```shell script
$ cat ~/.jjconfig
[user]
name = "Martin von Zweigbergk"
email = "martinvonz@google.com"
```
## Command-line completion
To set up command-line completion, source the output of
`jj debug completion --bash/--zsh/--fish`. Exactly how to source it depends on
your shell.

compdef _jj jj
```
### Fish
```shell script

```
