[CI][slang] Rename slang to slang-verilog

[JavierMatosD]

1. On repology this library is slang-verilog https://aur.archlinux.org/packages/slang-verilog
2. This port was dumping configs in share/slang which conflicts with another port (shader-slang) https://dev.azure.com/vcpkg/public/_build/results?buildId=127571&view=logs&j=f79cfdd7-47a8-597f-8f57-dc3e21a8f2ad&t=73c5513e-c47c-57a4-379a-581f7e429f13

@timkpaine It looks like the configs from this port were in conflict with another port in the registry. I see on repology that this library is referenced as slang-verilog so I'm proposing changing the port name to slang-verilog

@BillyONeal @vicroms I could revert the commit that adds this port and re-add it in a new PR?

I think for now we should just deindex it to limit the damage and effectively reopen the original PR.

To the best of my understanding renaming the port will not change this.
