ts: Fix loading programs with numbers in their names using workspace

[acheroncrypto]

Problem

Using numbers in program identifiers might result in problems when loading the program using anchor.workspace as explained here:

anchor/ts/packages/anchor/src/workspace.ts

Lines 27 to 42 in 6ff6655

	// Check whether the program name contains any digits
	if (/\d/.test(programName)) {
	// Numbers cannot be properly converted from camelCase to snake_case,
	// e.g. if the `programName` is `myProgram2`, the actual program name could
	// be `my_program2` or `my_program_2`. This implementation assumes the
	// latter as the default and always converts to `_numbers`.
	//
	// A solution to the conversion of program names with numbers in them
	// would be to always convert the `programName` to camelCase instead of
	// snake_case. The problem with this approach is that it would require
	// converting everything else e.g. program names in Anchor.toml and IDL
	// file names which are both snake_case.
	programName = programName
	.replace(/\d+/g, (match) => "_" + match)
	.replace("__", "_");
	}

When I initially was working on the above change, I first made it assume there is no _ involved e.g. if the user gives myProgram2, the program name is my_program2. However, with this change, the examples started failing because their names are basic_<number>, which then made me change it to its current form.

For example, if the program name is program_v2, and it's getting loaded with anchor.workspace.programV2, it results in the following error:

Error: target/idl/program_v_2.json doesn't exist. Did you run `anchor build`?

This is also one of the most commonly reported problems.
