Lowers test's account data size to avoid hitting MaxLoadedAccountsDataSizeExceed

[brooksprumo]

Problem

@jeffwashington informed me that #28690 was failing in CI due to an error in test_accounts_data_size_and_resize_transactions():
https://buildkite.com/solana-labs/solana/builds/85042#01847837-100f-41b7-af5a-fe94c67358f6

Running locally, I observed this test failing intermittently will this error:

[2022-11-15T14:29:15.554837000Z DEBUG solana_runtime::bank] tx error: MaxLoadedAccountsDataSizeExceeded SanitizedTransaction { message: Legacy(LegacyMessage { message: Message { header: MessageHeader { num_required_signatures: 1, num_readonly_signed_accounts: 0, num_readonly_unsigned_accounts: 1 }, account_keys: [J6MEcxb4f4oeePxv1RvzCyzhfXpi8SkJUAMfEWCLNSRh, 11111112cMQwSC9qirWGjZM6gLGwW69X22mqwLLGP, 7QmP1NzaR3SfDfKZBZ28LM6Wt4ii19AAFM2jMWcZJDg1, 1111111QLbz7JHiBTspS962RLKV8GndWFwiEaqKM], recent_blockhash: FpCi9pXxubub4F7qpceqpiPf8xPvkSvw6Rt8jELWAm3Q, instructions: [CompiledInstruction { program_id_index: 3, accounts: [2, 1], data: [0, 0, 0, 0, 89, 160, 64, 0, 0, 0, 0, 0, 0, 232, 118, 72, 23, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 5, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0] }] }, is_writable_account_cache: [true, true, true, false] }), message_hash: 9yxLvvz7xaQMm8cs5b3jGXsEm6xjZdn7MaEVbemmbssr, is_simple_vote_tx: false, signatures: [3tBZnNkr3Z7Rdk5dXxv1WWDvUkdzwWRYnqi5VG5wBKyRg8YiT1y2hmnAj7JNZghCEdH9hy1VMraRpawpNiazpDgv] }

This test grows and shrinks accounts to ensure their data size is tracked correctly by the bank. The initial data size and the grow/shrink size are randomly generated, which explains how this test could fail intermittently.

Zooming in, we see the error is MaxLoadedAccountsDataSizeExceeded, which is new as of #27840.

So test_accounts_data_size_and_resize_transactions() fails when the account size triggers MaxLoadedAccountsDataSizeExceeded.

Summary of Changes

Lower the bounds for the accounts size to ensure MaxLoadedAccountsDataSizeExceeded is not hit.
