Rename Cargo.toml to Cargo.text in the init template files

[elizabethengelman]

What

Updates the init template Cargo file from Cargo.toml to Cargo.text.

Why

We were seeing a failure with the dry-run:
https://github.com/stellar/soroban-cli/actions/runs/7983365311/job/21798405675

Slack thread with discussion about the problem: https://aha-labs.slack.com/archives/C04B02ABF37/p1708486449196609

This is due to a known cargo issue: rust-lang/cargo#9017

If a subdirectory includes a Cargo.toml file, it will be viewed as a sub-package, and therefore the contents of the directory will not be included in the package. Since we are including this Cargo.toml to be used as a template for writing a file to the user's fs, and it is not to be used as a sub-package, I've changed the name of the file to Cargo.text in this source code. Then when the file is being copied into the project that is being created on the user's machine, the file name is written as Cargo.toml, as expected.

From the cargo book docs:

Regardless of whether exclude or include is specified, the following files are always excluded:

Any sub-packages will be skipped (any subdirectory that contains a Cargo.toml file).
A directory named target in the root of the package will be skipped.

I tested this locally by recreating the steps in the dry-run, that @2opremio outlined in the slack convo, and was able to get through cargo-hack hack --feature-powerset --ignore-private --config "source.crates-io.replace-with = 'vendored-sources'" --config "source.vendored-sources.directory = 'vendor'" package without error.

Thanks!

I would personally use something more obvious, in the lines of Cargo.toml.removeextension or Cargo.toml.extensionworkaround

Great point. I'll push up a change shortly.

@elizabethengelman I just noticed that the Cargo.toml file at https://github.com/stellar/soroban-cli/tree/main/cmd/soroban-cli/src/utils/contract-init-template/contracts/hello_world should had been renamed too.
