[str replace] add exemple for escaped regexes (#14038)

Browse Source 
# Description

This is a follow-up of
https://github.com/nushell/nushell.github.io/pull/1584

The goal is to provide the user understanding of how to escape strings

# User-Facing Changes
Nothing except documentation

# Tests + Formatting
 
 I don't know why but these two tests are failing on my system:

- `test_std_util path_add`
- `commands::umkdir::mkdir_umask_permission`

Since I hardly believe it is linked to my changes, I will let your CI
check it. Meanwhile, I will check my system, highly likely that it is
something something related to me recently switching shells, hacking my
way through prompts environments, etc.


# After Submitting

Will check how to re-generate the [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged
