Document your linter

Each new linter must be accompanied by a documentation file in Markdown format. Create the documentation file corresponding to your linter in: elp/website/docs/erlang-error-index/w/W0055.md (where W0055 is the code we introduced):

# W0055 - Unsafe operation

This diagnostic warns about calls to `unsafe:operation/1`, which should be
avoided in production code due to potential security or stability risks.
`safe:operation/1` is a safer alternative that should be used instead.

## Example

```erlang showLineNumbers
-module(example).
-export([do/1]).

do(Data) ->
    unsafe:operation(Data).
%%  ^^^^^^^^^^^^^^^^^^^^^^ warning: Do not use unsafe:operation/1 in production code.
```

## Recommended fix

Replace calls to `unsafe:operation/1` with a safer alternative, such as
`safe:operation/1`.

```erlang
-module(example).
-export([do/1]).

do(Data) ->
    safe:operation(Data).
```

The documentation will be presented to the user in the IDE and will also be included in the Erlang Error Index.
