graphviz: updated to 7.0.4

7.0.4

Fixed

- The `alt` attributes are once again set in the cmap output. This was a
 regression in Graphviz 7.0.2, that intentionally removed these but did not
 account for the W3C specification making these attributes required when the
 `href` attribute is set.
- Building Graphviz from source using the Autotools build system in now possible
 on NetBSD.
- The ortho library now allocates trapezoid structures on-demand, removing the
 “Trapezoid-table overflow” error that previously occurred when its upfront
 estimation was exceeded.

7.0.3

Changed

* Support for the Intel C Compiler in the Autotools build system has been
 removed.
* Fallback typedefs for `ssize_t` have been removed from the CMake build system.
