Fixed missing referenced variables in the variableUsages field of fetch operations

Query variables used in fetch operation should be listed in the variableUsages field. However, there was a bug where variables referenced by query-level directives could be missing in the field.

The previous PR (#2986) fixed a similar issue in fetch queries, but it didn't fully fix the issue by failing to update the variableUsages field. This PR completes the remaining issue.

## @apollo/federation-internals@2.9.3

### Patch Changes

- fix: normalize field set selection sets
([#3162](#3162))

`FieldSet` scalar represents a selection set without outer braces. This
means that users could potentially specify some selections that could be
normalized (i.e. eliminate duplicate field selections, hoist/collapse
unnecessary inline fragments, etc). Previously we were using `@requires`
field set selection AS-IS for edge conditions. With this change we will
now normalize the `FieldSet` selections before using them as fetch node
conditions.

- Fixed missing referenced variables in the `variableUsages` field of
fetch operations
([#3166](#3166))

Query variables used in fetch operation should be listed in the
`variableUsages` field. However, there was a bug where variables
referenced by query-level directives could be missing in the field.

- Fix fragment generation recursion logic to apply minification on all
subselections.
([#3158](#3158))

- Fixed a bug that `__typename` with applied directives gets lost in
fetch operations.
([#3164](#3164))

The sibling typename optimization used by query planner simplifies
operations by folding `__typename` selections into their sibling
selections. However, that optimization does not account for directives
or aliases. The bug was applying the optimization even if the
`__typename` has directives on it, which caused the selection to lose
its directives. Now, `__typename` with directives (or aliases) are
excluded from the optimization.

## @apollo/query-graphs@2.9.3

### Patch Changes

- Fixes edge case where contextual arguments can yield inefficient query
plans. Also fixes naming of query plan arguments which can be a problem
when using contextual variables in multiple subgraphs
([#3140](#3140))

- When eliminating suboptimal indirect paths during query planning,
properly check for a direct `@key` edge at the end of the potential
direct path.
([#3160](#3160))

- Fixed missing referenced variables in the `variableUsages` field of
fetch operations
([#3166](#3166))

Query variables used in fetch operation should be listed in the
`variableUsages` field. However, there was a bug where variables
referenced by query-level directives could be missing in the field.

([#3140](#3140))

- Ensure all useless fetch groups are removed
([#3163](#3163))

When removing "useless" fetch nodes/groups we remove them in-place while
still iterating over the same list. This leads to potentially skipping
processing of some the children fetch nodes, as when we remove nodes we
left shift all remaining children but the iterator keeps the old
position unchanged effectively skipping next child.
