per ccoVeille's review, front matter only needs UTF-8 BOM handling, not
the full utfbom package. replace utfbom.Skip with a small unexported
stripUTF8BOM helper and add a stdin-path regression test alongside the
existing file-path one. utfbom stays in go.mod since decoder_csv_object.go
still uses it for CSV decoding.
--front-matter=process wrapped the file in a bufio.Reader without
skipping a leading UTF-8 BOM, so a BOM before the opening --- meant the
separator was not recognised and the opening --- was dropped from the
output (data loss). Skip the BOM with utfbom.Skip before wrapping the
reader, matching the CSV object decoder.
When using --front-matter, yq creates a temporary file for the
extracted YAML content but replaces the original filename in args
with the temp file path. This caused the 'filename' operator to
return the temp file path instead of the original filename.
Added a filename alias mechanism: when front matter processing
replaces the file path, it registers the original filename as an
alias. The readDocuments and stream evaluator functions resolve
aliases before setting candidateNode.filename.
Fixes#2538

* refactor: move from io/ioutil to io and os packages
The io/ioutil package has been deprecated as of Go 1.16, see
https://golang.org/doc/go1.16#ioutil. This commit replaces the existing
io/ioutil functions with their new definitions in io and os packages.
