add a "bug report" issue template

[amtoine]

description

i was trying to reproduce #40 and set $env.GIT_REPOS_HOME and $env.GIT_REPOS_CACHE to empty and unused directories and files to not mess up with my repositories.

in this PR, i propose to add an issue template for bug reports.
this is greatly inspired by the bug report of Nushell.

the template will ask for

• a description
• steps to reproduce: here it will be asked to define a clean reproduction environment using the following commands

const REPRO_ENV = {
    GIT_REPOS_HOME: ($nu.temp-path | path join "repos/"),
    GIT_REPOS_CACHE: ($nu.temp-path | path join "repos.cache"),
}

with-env $REPRO_ENV {
    gm status | select root.path cache.path | values | each {
        if ($in | path exists) { rm --recursive --force --verbose $in }
    }
}

and then run all the gm commands in with-env $REPRO_ENV { ... }

• what was expected
• the configuration of Nushell used
• (optional) some additional information

not sure we can test that before landing... so we might just want to bet and see how it looks like 😱

You can here, it's pretty much that minus the frontmatter:
