Re-add platform-specific packages for CI (#960)

some packages need to be re-installed on the target machine so that they
get the correct implementation.

In package-lock.json, we might have arm-version of
@nomicfoundation/solidity-analyzer, so that gets installed in CI machine
too. However, that machine needs the linux-x64-gnu version of the
package. This is fixed by running npm install on those specific
packages.

Specific error in CI, see e.g.
https://github.com/streamr-dev/network-contracts/actions/runs/13110417595/job/36585239309

`HardhatError: HH18: You installed Hardhat with a corrupted lockfile due
to the NPM bug #4828.`

NomicFoundation/hardhat#4937
suggests reason is "misidentifying the platform in
@nomicfoundation/solidity-analyzer"

After adding that package, another error appears: `Error: Cannot find
module 'solidity-comments-linux-x64-gnu'`

After adding that package as well, the run succeeds.
