Subject: [PATCH v2] Sphinx error fixed for inline literal end-string by changing $type_constant2 in kernel-doc script to include "*" unicode character in highlights_rst.

The kernel-doc script uses the $type_constant2 variable to match
expressions used to find embedded type information. The current
implementation of $type_constant2 does not include the "*" unicode
character, which is used to highlight inline literals in the
documentation. This causes a Sphinx error when the inline literal
end-string is used in the documentation.

This commit follows the pattern of the commit
8aaf297a0dd6 ("docs: scripts: kernel-doc: accept bitwise negation like ~@var")
and takes inspiration from the following commit
69fc23efc7e5 ("kernel-doc: Add unary operator * to $type_param_ref").

Thanks Akira, for your suggestions, I have made the required changes.
I am fairly new to the kernel community, so if I am making 
any mistakes while making patches and replying to mails,
please let me know, it will be very helpful.
