David Adam 02d82dcf85 docs: update all command synopsis formatting
Adds synopses for those commands missing them.

Moves all synopsis sections to code blocks. This improves the appearance, although highlighting as
fish code may not be the ideal appearance.

Description
-----------
With no arguments, ``status`` displays a summary of the current login and job control status of the shell.
The following operations (sub-commands) are available:
- ``is-command-substitution`` returns 0 if fish is currently executing a command substitution. Also ``-c`` or ``--is-command-substitution``.
- ``is-block`` returns 0 if fish is currently executing a block of code. Also ``-b`` or ``--is-block``.
- ``is-breakpoint`` returns 0 if fish is currently showing a prompt in the context of a ``breakpoint`` command. See also the ``fish_breakpoint_prompt`` function.
- ``is-interactive`` returns 0 if fish is interactive - that is, connected to a keyboard. Also ``-i`` or ``--is-interactive``.
- ``is-login`` returns 0 if fish is a login shell - that is, if fish should perform login tasks such as setting up the PATH. Also ``-l`` or ``--is-login``.
- ``is-full-job-control`` returns 0 if full job control is enabled. Also ``--is-full-job-control`` (no short flag).
- ``is-interactive-job-control`` returns 0 if interactive job control is enabled. Also, ``--is-interactive-job-control`` (no short flag).
- ``is-no-job-control`` returns 0 if no job control is enabled. Also ``--is-no-job-control`` (no short flag).
- ``current-command`` prints the name of the currently-running function or command, like the deprecated ``_`` variable.
- ``filename`` prints the filename of the currently running script. Also ``current-filename``, ``-f`` or ``--current-filename``.
- ``fish-path`` prints the absolute path to the currently executing instance of fish.
- ``function`` prints the name of the currently called function if able, when missing displays "Not a
function" (or equivalent translated string). Also ``current-function``, ``-u`` or ``--current-function``.
- ``line-number`` prints the line number of the currently running script. Also ``current-line-number``, ``-n`` or ``--current-line-number``.
- ``stack-trace`` prints a stack trace of all function calls on the call stack. Also ``print-stack-trace``, ``-t`` or ``--print-stack-trace``.
- ``job-control CONTROL-TYPE`` sets the job control type, which can be ``none``, ``full``, or ``interactive``. Also ``-j CONTROL-TYPE`` or ``--job-control=CONTROL-TYPE``.
- ``features`` lists all available feature flags.
- ``test-feature FEATURE`` returns 0 when FEATURE is enabled, 1 if it is disabled, and 2 if it is not recognized.
Notes
-----
For backwards compatibility each subcommand can also be specified as a long or short option. For example, rather than ``status is-login`` you can type ``status --is-login``. The flag forms are deprecated and may be removed in a future release (but not before fish 3.0).
You can only specify one subcommand per invocation even if you use the flag form of the subcommand.
