GHA/linux: allow more time for apt.repos.intel.com install

Whether the install is extreme slow and will fail anyway, or only slower
sometimes, and this fixes, we will see.

Example:
```
Need to get 1159 MB of archives.
After this operation, 4463 MB of additional disk space will be used.
Get:1 https://apt.repos.intel.com/oneapi all/main all intel-oneapi-common-licensing-2023.2.0 all 2023.2.0-49462 [30.4 kB]
Get:2 https://apt.repos.intel.com/oneapi all/main all intel-oneapi-common-licensing-2026.0 all 2026.0.0-235 [30.7 kB]
[...]
