Exclude pnpm from template- renovates

[samchungy]

#1703

 ERROR  This project is configured to use v9.12.0 of pnpm. Your current pnpm is v9.12.1
If you want to bypass this version check, you can set the "package-manager-strict" configuration to "false" or set the "COREPACK_ENABLE_STRICT" environment variable to "0"

Not sure if this will make it available it in the repo level pnpm updates but we can always test it.
