ReadmeCard component height

[dimapasko]

Describe the feature

At present, configuring the height of the ReadmeCard is not supported.

According to this code, the height can only be set to either 235px (which may be too small) or full screen (which requires a specific layout).

Could the option to adjust the component height be added?

Added value

ReadmeCard will be more customizable and adaptable to various layouts.
