Detecting changed files is broken in v1.1.0

[aabouzaid]

Hello,

because of the latest change in v1.1.0, now charts_dir doesn't work with "." (current working directory)

chart-releaser-action/cr.sh

Line 228 in c3d308d

local depth=$(( $(tr "/" "\n" <<< "$charts_dir" | wc -l) + 1 ))

This expression cannot be less than 2 that's why no changes detected in the current working directory.

$ echo $(( $(tr "/" "\n" <<< "." | wc -l) + 1 )) 
2

The + 1 should be removed.

I can confirm that issue.

I also faced this issue after upgrading version to 1.1.0
Downgraded the chart-releaser-action version to 1.0.0 for now

Still seems to be present in 1.2.0.
