CompatHelper: bump compat for JuliaSyntax to 1, (keep existing compat)

[github-actions]

This pull request changes the compat entry for the JuliaSyntax package from 0.4 to 0.4, 1.
This keeps the compat entries for earlier versions.

Note: I have not tested your package with this new compat entry.
It is your responsibility to make sure that your package tests pass before you merge this pull request.

This is not a trivial fix, for now, I'll write down some potential changes required, and come back when I have time.

• true, false are no longer tokenized as two separate kinds of tokens, but the same token K"Bool" (Replace K"true" and K"false" with K"Bool" JuliaLang/JuliaSyntax.jl#488)
• <- is parsed differently
  • v0.4.10

    julia> tokenize("p <- dnorm(0, 1)")
    12-element Vector{Token}:
     Token(JuliaSyntax.SyntaxHead(K"Identifier", 0x0000), 0x00000001:0x00000001)
     Token(JuliaSyntax.SyntaxHead(K"Whitespace", 0x0001), 0x00000002:0x00000002)
     Token(JuliaSyntax.SyntaxHead(K"<", 0x0000), 0x00000003:0x00000003)
     Token(JuliaSyntax.SyntaxHead(K"-", 0x0000), 0x00000004:0x00000004)
     Token(JuliaSyntax.SyntaxHead(K"Whitespace", 0x0001), 0x00000005:0x00000005)
     Token(JuliaSyntax.SyntaxHead(K"Identifier", 0x0000), 0x00000006:0x0000000a)
     Token(JuliaSyntax.SyntaxHead(K"(", 0x0001), 0x0000000b:0x0000000b)
     Token(JuliaSyntax.SyntaxHead(K"Integer", 0x0000), 0x0000000c:0x0000000c)
     Token(JuliaSyntax.SyntaxHead(K",", 0x0001), 0x0000000d:0x0000000d)
     Token(JuliaSyntax.SyntaxHead(K"Whitespace", 0x0001), 0x0000000e:0x0000000e)
     Token(JuliaSyntax.SyntaxHead(K"Integer", 0x0000), 0x0000000f:0x0000000f)
     Token(JuliaSyntax.SyntaxHead(K")", 0x0001), 0x00000010:0x00000010)

  • 1.0.2

    julia> tokenize("p <- dnorm(0, 1)")
    12-element Vector{Token}:
     Token(JuliaSyntax.SyntaxHead(K"Identifier", 0x0000), 0x00000001:0x00000001)
     Token(JuliaSyntax.SyntaxHead(K"Whitespace", 0x0001), 0x00000002:0x00000002)
     Token(JuliaSyntax.SyntaxHead(K"Identifier", 0x0000), 0x00000003:0x00000003)
     Token(JuliaSyntax.SyntaxHead(K"Identifier", 0x0000), 0x00000004:0x00000004)
     Token(JuliaSyntax.SyntaxHead(K"Whitespace", 0x0001), 0x00000005:0x00000005)
     Token(JuliaSyntax.SyntaxHead(K"Identifier", 0x0000), 0x00000006:0x0000000a)
     Token(JuliaSyntax.SyntaxHead(K"(", 0x0001), 0x0000000b:0x0000000b)
     Token(JuliaSyntax.SyntaxHead(K"Integer", 0x0000), 0x0000000c:0x0000000c)
     Token(JuliaSyntax.SyntaxHead(K",", 0x0001), 0x0000000d:0x0000000d)
     Token(JuliaSyntax.SyntaxHead(K"Whitespace", 0x0001), 0x0000000e:0x0000000e)
     Token(JuliaSyntax.SyntaxHead(K"Integer", 0x0000), 0x0000000f:0x0000000f)
     Token(JuliaSyntax.SyntaxHead(K")", 0x0001), 0x00000010:0x00000010)

  i.e., <- is now parsed as two K"Identifier" instead of K"<" and K"-", but this is something I relied on in the
  parser

Figure out:

• What version of JuliaSyntax is Julia 1.10 using? How about Julia 1.2? (This is potentially related to when I must fix this)
• Even if in a future version of Julia when JuliaSyntax 1.0 is used, must I update from JuliaSyntax 0.4, or both version can be used?
