Possibly incorrect and confusing JSDoc for near-api-js/lib/account.d.ts

[ryancwalsh]

Hi team! 😃 ⋈ Ⓝ

Describe the bug
I'm wondering if the JSDoc in node_modules/near-api-js/lib/account.d.ts might be incorrect. It doesn't match what is written at https://docs.near.org/concepts/basics/accounts/access-keys (which the JSDoc itself links to).

In particular, I'm looking at the methodNames and amount arguments, which say:

* @param methodNames The method names on the contract that should be allowed to be called. Pass null for no method names and '' or [] for any method names.
* @param amount Payment in yoctoⓃ that is sent to the contract during this function call

1. Because of https://docs.near.org/concepts/basics/accounts/access-keys, I was surprised that amount wasn't called allowance, with this description:

allowance: The amount of Ⓝ allowed to spend on gas (Optional). If omitted, the key will only be allowed to call view methods (read-only).

2. I've tried passing null for methodNames, and I think it behaves the same as when I pass []. I.e. Either way, the output of const keys = await account.getAccessKeys(); shows [] for methodNames.

Can you please let me know if I'm misunderstanding? Thanks!
