[FEAT] Let users modify precision in DataFrame serializer

[GSTALTER Guillaume]

Is your feature request related to a problem? Please describe.
Currently, the precision of values in a dataframe is set to 2 and cannot be changed by the user. This does not fit well for values that deserve higher precision (highly dependent on the data).

Describe the solution you'd like
Ideally, the user would be able to overwrite the display precision when exporting the suite result, via a dedicated parameter.

Code block: deepchecks/core/serialization/dataframe/html.py
