the `wp cli i18n` command encounters errors when trying to manipulate files

## Description

When attempting to generate a `.pot` file from a file or theme the `wpcli i18n` command encounters errors.

### First Round

Initially the error encountered was due to PHP memory being exhausted.

`wpcli i18n make-pot . `
`````
PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 4096 bytes) in phar:///usr/local/bin/wp/vendor/mck89/peast/lib/Peast/Syntax/CommentsRegistry.php on line 172
`````

The assumption is that there may be something amiss with the command argument flags being absent or incorrect OR the `docker-compose.yml` configuration, or possibly both.

## Reproduction

1. run command `wpcli i18n make-pot . `
2. See error.

## Expectation

the `i18n` command should work as documented and allow the generation of a `.pot1` file.
