chore: fix usage of dependant where should be dependent

[kevinheavey]

Basically dependant is a noun and dependent is an adjective. There are some places where dependent should be used instead of dependant.

There are also a bunch of cases in the repo where it's not clear which word was intended, but the cases in this PR are clear.

Thanks @kevinheavey, changes look good to me.

There are also code variables that could be updated in this PR

lodestar/packages/beacon-node/src/chain/lightClient/index.ts

Line 39 in c9226e1

type DependantRootHex = RootHex;

lodestar/packages/beacon-node/src/chain/opPools/aggregatedAttestationPool.ts

Line 453 in c9226e1

let attestationDependantRoot: string;

According to beacon API spec, this should be called DependentRoot and dependent_root

Just noticed, if you search for "dependant root" you will find a bunch more that should be changed. I checked the consensus and beacon spec, there is no such thing as dependant root.

lgtm, thanks @kevinheavey
