doc: escape braces in AsciiDoc

Browse Source 
This commit fixes a bug where AsciiDoc would drop any line containing a
'{foo}' because it interpreted it as an undefined attribute reference:

> Simple attribute references take the form {<name>}. If the attribute name
> is defined its text value is substituted otherwise the line containing the
> reference is dropped from the output.

See: https://www.methods.co.nz/asciidoc/chunked/ch30.html

We fix this by simply replacing all occurrences of '{' and '}' with
their escaped forms: '&#123;' and '&#125;'.

Fixes #1101

The format of the flag is `{type}:{attribute}:{value}`. `{type}` should be

'{value}' is either a color (for fg and bg) or a text style. A special format,

For example, the following command will change the match color to magenta and
the background color for line numbers to yellow:
rg --colors 'match:fg:magenta' --colors 'line:bg:yellow' foo.

Extended colors can be used for '{value}' when the terminal supports ANSI color
sequences. These are specified as either 'x' (256-color) or 'x,x,x' (24-bit
truecolor) where x is a number between 0 and 255 inclusive. x may be given as
a normal decimal number or a hexadecimal number, which is prefixed by `0x`.
