Support read-only file systems

https://github.com/OpenZeppelin/openzeppelin-upgrades/blob/e914ea305bdb4e9bd1afd917ba2a223dc1d9c0ff/packages/plugin-hardhat/src/utils/validations.ts#L14

I believe the error is caused by the above function.
I am using Google App Engine to host my deploy function (which will deploy an upgradable contract to Matic). It works fine with I tested in in my local Mac environment. However, when I trigger the login in Google App Engine, I see this error. I would like to ask if there is any solution for this?

[Error: EROFS: read-only file system, mkdir '/workspace/cache/validations.json.lock'] {
 errno: -30,
code: 'EROFS',
syscall: 'mkdir',
path: '/workspace/cache/validations.json.lock'
}

Start with packages/plugin-hardhat/src/utils/validations.ts at line 14 and reproduce the deployment in Google App Engine, where the filesystem is read-only. Trace how cache/validations.json.lock is created and define the expected behavior for that environment; the issue is done when the deployment no longer fails with EROFS.
