Matt Valentine-House b6390a21eb [ci skip] More docs for InstructionSequence.compile 
This commit documents that you can also pass a `File` object to
`RubyVM::InstructionSequence.compile`, instead of a string, and this
will behave in a similar way to
`RubyVM::InstructionSequence.compile_file`

e.g.

```
❯ ./ruby -e "puts RubyVM::InstructionSequence.compile(File.open('test.rb')).disasm"
== disasm: #<ISeq:<compiled>@<compiled>:1 (1,0)-(2,21)>
local table (size: 1, argc: 0 [opts: 0, rest: -1, post: 0, block: -1, kw: -1@-1, kwrest: -1])
[ 1] name@0
0000 putstring                              "Ruby"                    (   1)[Li]
0002 setlocal_WC_0                          name@0
0004 putself                                                          (   2)[Li]
0005 putobject                              "Hello, "
0007 getlocal_WC_0                          name@0
0009 dup
0010 objtostring                            <calldata!mid:to_s, argc:0, FCALL|ARGS_SIMPLE>
0012 anytostring
0013 concatstrings                          2
0015 opt_send_without_block                 <calldata!mid:puts, argc:1, FCALL|ARGS_SIMPLE>

```

This is explicitly allowed by this code path in
`rb_iseq_compile_with_option` so we should document it.

```
    if (RB_TYPE_P(src, T_FILE)) {
        parse = rb_parser_compile_file_path;
    }
    else {
        parse = rb_parser_compile_string_path;
        StringValue(src);
    }
```

What is Ruby?

Ruby is an interpreted object-oriented programming language often used for web development. It also offers many scripting features to process plain text and serialized files, or manage system tasks. It is simple, straightforward, and extensible.

Features of Ruby

  • Simple Syntax
  • Normal Object-oriented Features (e.g. class, method calls)
  • Advanced Object-oriented Features (e.g. mix-in, singleton-method)
  • Operator Overloading
  • Exception Handling
  • Iterators and Closures
  • Garbage Collection
  • Dynamic Loading of Object Files (on some architectures)
  • Highly Portable (works on many Unix-like/POSIX compatible platforms as well as Windows, macOS, etc.) cf. https://docs.ruby-lang.org/en/master/maintainers_md.html#label-Platform+Maintainers
