docs(core): restructure guides into technologies sections (#31288)
Updates the docs structure, navigation etc to be easier + better suited
for showing Nx technology support beyond just TS.

**Notes:**

- API (`/nx-api`) tab is removed from the navigation (i.e. menu bar),
but pages still remain for now until we update references in `*.md`
files.
- Redirects are set up `/nx-api` to go to their respect new location
e.g. `/technologies` or `/reference/core-api`
- Old URLs still exist in the sitemap for now, but majority of them will
be redirected -- a follow-up PR can remove them.

**Preview:**

Function: applyChangesToString

applyChangesToString(text, changes): string

Applies a list of changes to a string's original value.

This is useful when working with ASTs.

For Example, to rename a property in a method's options:

const code = `bootstrap({
  target: document.querySelector('#app')
})`;

const indexOfPropertyName = 13; // Usually determined by analyzing an AST.
const updatedCode = applyChangesToString(code, [
  {
    type: ChangeType.Insert,
    index: indexOfPropertyName,
    text: 'element',
  },
  {
    type: ChangeType.Delete,
    start: indexOfPropertyName,
    length: 6,
  },
]);

bootstrap({
  element: document.querySelector('#app'),
});

Parameters
