chore: fix EditorConfig lint errors

[dchaudhari7177]

Resolves #15088.

Description

This pull request:

• re-indents lines 39–51 of lib/node_modules/@stdlib/_tools/eslint/rules/no-builtin-math/examples/index.js with tabs instead of spaces.

The /* => ... */ example-output block used 4-space indentation, while .editorconfig sets indent_style = tab for [*.{js,js.txt}]. Each level is replaced by one tab at the same depth (4→1, 8→2, 12→3), so the rendered block is unchanged in structure.

Verified with editorconfig-checker against the repository's own .editorconfig:

BEFORE  before.js:
          39-51: wrong indentation type (spaces instead of tabs)
        1 errors found

AFTER   (no output, exit 0)

That matches the workflow error in the issue exactly. I also confirmed the change is whitespace-only: diff <(tr -d ' \t' < before.js) <(tr -d ' \t' < after.js) is empty.

I used an AI assistant to locate the flagged lines and apply the re-indentation, then verified the result myself by running editorconfig-checker against the repository's .editorconfig on both the original and the patched file, and by confirming the diff is whitespace-only.
