Exported png files are very low resolution

[zioalex]

Describe the bug
When converting a mermaid file to png the resolution of the text is very low.
Didn't find any way to change the resolution of the output file.

To Reproduce
Steps to reproduce the behavior:

1. Run mmdc -i process1.mmd -o process1.png -p ./puppepteerConfigFile.json
2. check process1.png

Expected behavior
The png created should be high enough resolution to read clearly the text
