style(hooks): copyright year check as per author email

Add a check in pre-commit hook to check the
- copyright header is present for the authors organisation.
- the copyright year for the copyright header is updated.

The author email id is parsed to get the organization. Depending upon
the parsed info, the copyright header for the organization is checked
if its present in the file(s) or not.
If the copyright header is present in the file(s) then the copyright
year is checked.

If the copyright header is not present or the copyright year in the
header is not updated it is highlighted to the author
which the user then needs to incorporate in the change accordingly.

To enable this check, the case statement in
.husky/pre-commit.copyright needs to be modified to add the domain
from the email id and corresponding copyright header of the
organisation.
