Smart crop add an extra space in _formatted field

[alallema]

Describe the bug
The smart crop add an extra space in the _formatted field.

To Reproduce
Steps to reproduce the behavior:

1. Send a search request with this parameters

{
	"q": "to",
	"attributesToCrop": ["Title"],
	"cropLength": 2,
	"cropMarker": "(ꈍᴗꈍ)"
}

2. Get this result on the v0.28.0rc0

    "Title": "(ꈍᴗꈍ)Guide to (ꈍᴗꈍ)",

3. When I had this result with v0.27.1

    "Title": "(ꈍᴗꈍ)Guide to(ꈍᴗꈍ)",

Expected behavior
I'm not sure if this behavior is expected, but even if it is, it's more complicated to remove an extra space than to add one directly in the cropMarker.

Meilisearch version: v0.28.0rc0

Hello @alallema thanks for your issues

@ManyTheFish let us know if it's expected 😇

hey @curquiza and @alallema!
I think that the behavior expectation is fulfilled until we return the good amount of words.
However, I can make a PR forcing the new formater to trim spaces. 😄

With the crop marker it is clearer that it is a bit weird:

…book about a prince that walks …

It will be fixed in rc1! 😄
