[Error] assemble does not work with hyphenated container names as expected

[askoa]

Describe the bug distrobox-assemble uses grep -qw to check if the container already exist.

https://github.com/89luca89/distrobox/blob/4c38d6b3f9bc833e58a435471158935824727805/distrobox-assemble#L328

According to the grep manual page, the option -w does not consider hyphens to be "Word-constituent characters"

       -w, --word-regexp
              Select only those lines containing matches that form whole
              words.  The test is that the matching substring must
              either be at the beginning of the line, or preceded by a
              non-word constituent character.  Similarly, it must be
              either at the end of the line or followed by a non-word
              constituent character.  Word-constituent characters are
              letters, digits, and the underscore.  This option has no
              effect if -x is also specified.

When there is a container named prototype-dev and if the user is attempting to create a container named dev using command distrobox assemble create --name dev --file <file>, the user will get an error message container dev already exist which is wrong.

To Reproduce

1. Create a distrobox container named prototype-dev
2. Attempt to create a container named dev by running distrobox assemble create --name dev --file <file>

Expected behavior distrobox assemble should create the container named dev.

Logs

I was also affected by this. Nice write-up of the situation.
