BUG: Flag <SHOW_LOC_CHART: "True"> Failed

[liumy-lay]

Describe the bug
The version I Used: anmol098/waka-readme-stats@master

If the Flag SHOW_LOC_CHART is not filled in in YML, the default is "True" .

At the beginning of Github Action Faild, I couldn't find something wrong,

but when I added show_loc_chart: "Flase", GitHub Action was successful.

Here is the detailed bug description：

Expected behavior

For new users of Wakatime，to avoid ACTION FAILED the flag SHOW_LOC_CHART should set to False by default in the original code.

Same error with SHOW_LOC_CHART = False.
