Add note in readme that content search examples are non-fuzzy

[tobx]

Section As Interactive Interface states:

Normally you would want to integrate it with grep, ack, ag, or rg for searching contents in a project directory

The examples below show non-fuzzy file content searching. Switch to fuzzy mode (Control + Q) is possible, but I think not what you "normally" want. I think this leads to confusion. I took me a long time to understand what is going on here and that I am actually not using fuzzy search. See also #212.

I understand now that you can use skim only as an interface for other search tools and that is exactly what the headline says, but for me at least the examples led to confusion. Why would I "normally" use grep-like tools if I have skim?

I would recommend to add a note under those examples. Something like:

Note: Those examples show how to replace skim's search engine with other tools and use skim as an interface only. Fuzzy searching through file contents can for example be achieved with:

rg '' --color=always --line-number | sk --ansi

(probably there are better options than rg to simply pass file contents with line numbers to skim that I don't know of)
