Incorrect treatment of <%== %> in html.erb files

[beniutek]

Hello

It looks like (using version 0.4.0) prettier plugin erb is not handling correctly things like

<%== 'something' %>

when running prettier it will signal files containing that code and when --write option is passed it will attempt to rewrite it to

<%= = 'something' %>

<%== is a valid html.erb thing (check https://edgeguides.rubyonrails.org/active_support_core_extensions.html#safe-strings )
and it simply is an equivalent of raw method.

The workaround is to use

<%= raw('something') %>
