v1.5.0

What's Changed

Support of Tact 1.5.0 in #40:

• feat: uint1-256 and int1-256 through highlighting queries
• chore: remove highlighting of built-in functions, since functions in Tact aren't first-class
• feat: add new builtin constants and structs, and update tests
• feat: limited support of asm functions
• chore: bump versions to 1.5.0
• feat: optional semicolon for the last field or function declaration in trait/contract bodies
• fix(CI): test tree-sitter-tact against the same version of the Tact compiler
