bug: ASDF_DEFAULT_TOOL_VERSIONS_FILENAME env variable works so wired

[siuyutpang]

Describe the Bug

I just don't want .tool-version clutter my home dir, So I set export ASDF_DEFAULT_TOOL_VERSIONS_FILENAME="$XDG_CONFIG_HOME"/asdf/tool-versions in .zshrc file, Everything looks fine, but when i use asdf set global version, error occurs, but when i set export ASDF_DEFAULT_TOOL_VERSIONS_FILENAME=.config/asdf/tool-versions, everything works well.

Steps to Reproduce

asdf global maven 3.9.6

Expected Behaviour

set correct global version for maven

Actual Behaviour

/opt/asdf-vm/lib/functions/versions.bash: line 78: /home/foobar//home/foobar/.config/asdf/tool-versions: No such file or directory

I am experiencing the same issue.

For me the issue occurs with command: asdf local ruby 3.2.2

/home/vlada/.local/share/asdf/lib/functions/versions.bash: line 78: /home/foorbar/path-to-current-directory//home/foobar/.config/asdf/tool-versions: No such file or directory

It seems like the path to current directory is added to the ASDF_DEFAULT_TOOL_VERSIONS_FILENAME.
