solana-ledger-tool error: Unable to increase the maximum open file descriptor limit to 1000000 from 1024

Problem

$ solana-ledger-tool program run -l test-ledger -e debugger ../program-examples/basics/hello-solana/native/program/target/so/hello_solana_program.so

Failed to open blockstore at "/home/solana-test-validator/test-ledger": UnableToSetOpenFileDescriptorLimit

Proposed Solution

One way(as suggested by Sean) to solve is to increase the prlimit e.g.,

$ sudo prlimit -p $$ --nofile=1000000

We should add this in the doc.

Note: There was a related issue #19575 with the validator. The fix has been documented in https://docs.solanalabs.com/operations/guides/validator-start#system-tuning, other solutions were also proposed in the issue itself e.g., #19575 (comment). But it may not be obvious to users of solana-ledger-tool so we should add relevant documentation.
