docs: Clarify directory reference Update README.md

[mdqst]

Description:

Issue in the bedrock-devnet documentation. The original phrasing:

"if you are invoking the script from somewhere other than bedrock-devnet"

has been updated to:

"if you invoke the script from somewhere other than the bedrock-devnet directory"

The revised version explicitly refers to the directory, avoiding potential confusion about whether bedrock-devnet refers to the directory or the script itself.

Love OP L2
