John-David Dalton 87a677c811 Update lodash-amd to v4.17.21 + edadd45 (#6064)
* Fix prototype pollution in _.set and related functions

Prevents setting dangerous properties (__proto__, constructor, prototype)
that could lead to prototype pollution vulnerabilities.

* Fix command injection vulnerability in _.template

- Add validation for the variable option to prevent injection attacks
- Improve sourceURL whitespace normalization to prevent code injection

* Fix cyclic value comparison in _.isEqual

Properly checks both directions when comparing cyclic values to ensure
correct equality comparisons for circular references.

* Improve _.sortBy and _.orderBy performance and array handling

- Add early return for empty arrays in sorted index operations
- Improve array iteratee handling to support nested property paths
- Add missing keysIn import in baseClone

* Refactor _.trim, _.trimEnd, and _.trimStart implementations

Extract shared trim logic into reusable utilities (_baseTrim, _trimmedEndIndex)
for better code organization and consistency. Update related functions
(toNumber, parseInt) to use new utilities. Improve comment accuracy.

* Add documentation for predicate composition with _.overEvery and _.overSome

Enhance documentation to show how _.matches and _.matchesProperty can be
combined using _.overEvery and _.overSome for more powerful filtering.
Add examples demonstrating shorthand predicate syntax.

* Bump to v4.17.21

* Fix prototype pollution in _.unset and _.omit

Prevent prototype pollution on baseUnset function by:
- Blocking "__proto__" if not an own property
- Blocking "constructor.prototype" chains (except when starting at primitive root)
- Skipping non-string keys

See: https://github.com/lodash/lodash/security/advisories/GHSA-xxjr-mmjv-4gpg

* Update JSDoc documentation to align with main branch

- Fix sortBy example ages (40 -> 30) for correct sort order demonstration
- Fix _setCacheHas return type (number -> boolean)
