Update c-api-noopenmp-packaging-pipelines.yml: remove CUDA version parameter (#20955)
### Description
Update c-api-noopenmp-packaging-pipelines.yml: remove CUDA version
parameter
To reduce confusion. This pipeline is for generating CUDA 11 packages.
Just it. Not CUDA 12.
### Motivation and Context
In the last release we accidentally published CUDA 12(instead of CUDA
11) packages to nuget.org.
We also tried to publish CUDA 12 packages to
https://aiinfra.visualstudio.com/PublicPackages/_artifacts/feed/ORT-Nightly.
Luckily it didn't go through because a package with the same version
number already existed there. Every time when someone runs this pipeline
with CUDA version set to 12, the built packages will be published to
https://aiinfra.visualstudio.com/PublicPackages/_artifacts/feed/ORT-Nightly.
And GenAI team's build pipelines are based on the nightly packages. So
sometimes GenAI team builds their packages with CUDA 12 and sometimes
with CUDA 11, which is very random.
Therefore, please limit the use of pipeline parameters. Most Azure
DevOps yml files are template files. They should use parameters. But the
top level yml files should be more careful on that.
