Unsupported escaped characters \a and \/

[apstndb]

Describe the bug

Escaped characters \a and \/ are not supported.
They are documented here.
https://yaml.org/spec/1.2.2/#57-escaped-characters

Escaped ASCII bell (x07) character.

[43] ns-esc-bell ::= 'a'

scaped ASCII slash (x2F), for JSON compatibility.

[53] ns-esc-slash ::= '/'

To Reproduce
https://go.dev/play/p/LyP5F1vUARi

Expected behavior
All escaped characters are supported.

Version Variables

• Go version: Go 1.23.2
• go-yaml's Version: v1.15.4

Additional context

I've found this incompatibility in testcases of bufbuild/protoyaml-go.
This appears to be explicitly tested, since string of Protocol Buffers also supports \a.

https://protobuf.dev/reference/protobuf/edition-2023-spec/#string_literals

charEscape = '\' ( "a" | "b" | "f" | "n" | "r" | "t" | "v" | '\' | "'" | '"' )
